ATI CrossFireX versus NVIDIA SLI: performance scaling showdown
We know who the daddy is when it comes to single-card graphics performance, and we've even witnessed NVIDIA and ATI duking it out with multiple cards before, but this here roundup is what you might call comprehensive. Comparing a mind-boggling 23 different configurations, the Tech Report guys set out to determine the best bang for your DirectX 11 buck. Their conclusion won't shock those of you who've been following the recent love affair between reviewers and NVIDIA's GeForce GTX 460: a pair of these eminently affordable cards regularly outpaced the best single-GPU solutions out there. Slightly more intriguing, however, was the discovery that its elder siblings, the GTX 470 and 480, have improved in performance to the point of being markedly ahead of ATI's Radeon HD 5870, with the blame for this shift being put squarely on the shoulders of NVIDIA's driver update team. Hurry up and give the source a read while it's still fresh, we can't imagine ATI letting this be the status quo for too much longer.
ASUS Mars 2 teases superpowered dual GeForce GTX 480 goodness
We'll be honest with you, we thought the GTX 480 was finally a graphics core too damn large and power-hungry to get the dual-GPU treatment. ASUS, however, is making us think again. Imagery has emerged of a Mars 2 (or II, if you're into outdated numbering schemes) reference board that fits two 480s on its densely populated surface, and is fed by not one, not two, but three 8-pin auxiliary power connectors. Back when Galaxy showed off a dual-GTX 470 prototype at Computex a month ago, we deemed it an unreasonable proposition -- in terms of power draw, heat dissipation, and cost -- but apparently those Taiwanese focus groups are really into their extravagantly overpowered video cards. We suspect if and when this Mars 2 hits retail it'll do so in a highly exclusive fashion, like its predecessor, and anticipate the unveiling of its cooler -- which is likely to be either the biggest or best engineered one we've seen yet.
NVIDIA GeForce GTX 480M reviewed: fastest mobile GPU to date
It's one thing to have a product called the world's fastest on paper, but it's another thing entirely to have the benchmarks confirm it. NVIDIA's GeForce GTX 480M has been swooned over for months now, but it just recently hit the hardcore review sites in a big way. Frankly, there's not a whole lot to say about the thing at this point: it's simply the fastest mobile GPU to date, with Hot Hardware finding it to be "significantly faster in nearly all gaming benchmarks," with just one title showing the Mobility Radeon HD 5870 as the champ by only a few frames. If you've been searching for the fastest mobile GPU in town, you're wasting your time looking any harder; 'course, all of that power consumes an insane level of energy, so true road warriors will certainly want to look elsewhere. Critics pointed out that energy consumption and excess heat were real issues, though both of those are easily overlooked when you're able to take a beastly laptop to a LAN party rather than your desktop. Give those links below a visit if you still need proof.
NVIDIA GeForce GTX 480M breaks cover, frags competition in 3DMark
We told you NVIDIA's all-new superpowered mobile GPU would only fit inside jumbo-sized cases and here's your proof. The Clevo Style Note D900 is neither stylish nor much of a note taker, but boy it's a big, bad gaming machine. That trifecta of fans you see above is cooling the GTX 480M chip as well as a 2.93GHz Core i7-940 -- a CPU that's designed for desktop duty from what we can gather. You won't be shocked to discover this 17-inch desktop replacement rather burned the feathers off some similarly juiced up high fliers, but the difference is of course that laptops like the ASUS G73JH are actually available to buy, as opposed to a pipe dream demo machine like the Clevo. All the same, you might wanna check out this sneak peak before HH does a full review. Update: Turns out Sager is already offering to furnish you with a GTX 480M-equipped rig that looks very much like this one, including a selection of desktop-class Core i7s. [Thanks, Barry]
NVIDIA brings a dual GTX 470 prototype to Computex, causes power shortages in Taipei
We'll hit the pause button on all the power-sipping tablet talk for a moment to show you NVIDIA's maddest and baddest beast yet. This is a dual GeForce GTX 470 card, meaning that two Fermi dies reside on the same board, along with the necessary circuitry and an apparently beefed up apportionment of GDDR5 RAM as well. Measuring in at 12 inches long, this prototype is being shown off at Computex by add-in board partner Galaxy -- probably just to prove that the mammoth undertaking is even possible. You'll be forgiven for mistaking it for one of 3dfx's final ill-fated productions, and with a requirement for two 8-pin power connectors and a doubling of the standard 470's 215W TDP, this dualie card sure looks set for a similar future of pretty pictures and no retail viability. All the same, if you happen to have a nuclear reactor and a wind farm in your backyard, this could be just the GPU for you.
NVIDIA GeForce GTX 465 rounds up mostly positive reviews
Well, it's not quite June 1, but the GeForce GTX 465 reviews have come flooding out all the same. The official specs are exactly as a recent leak indicated: 352 CUDA cores running at 1,215MHz, a 607MHz graphics clock, and 1GB of GDDR5 memory operating at a 3.2GHz effective rate and exploiting a 256 bit-wide interface. With an MSRP of $279.99, this Fermi-lite GPU scored plenty of admiration for the value it offers, with one reviewer going so far as to call it "quite possibly the most powerful DirectX 11 graphics card for under $300." Others weren't so enthusiastic, citing the far cheaper HD 5830 from ATI as a better choice, but it's true enough that the next best GPU, the HD 5850, tends to be at least $30 more expensive than the 465, depending on brand. You'll want to delve into the game benchmark numbers in order to make up your mind about which card might make for the best bit, but be warned that NVIDIA's 465 retains the GTX tradition of ravenous power consumption -- something to consider if you're rolling along with an old school 400W PSU in your rig.

NVIDIA GeForce GTX 480M: 'world's fastest' mobile GPU now official, landing in June
NVIDIA has just announced that the GTX 480M, the mobile re-spin of its extravagantly overpowered Fermi desktop parts, will be arriving in the middle of next month. Touted as the world's fastest mobile graphics processor, this chip will bring 352 CUDA cores and a 256-bit memory interface to up to 2GB of GDDR5 RAM. These are clear and convincing advances over the incumbent Green Team leader, the 360M, but things start to look a little worrying when we check the 480M's clock speeds. The processor speed is nearly halved from the desktop GTX 480, at 850MHz, the memory does only 1,200MHz, and the graphics run at 425MHz -- we didn't know anything worthwhile even operated below 500MHz these days. Either way, you're getting a computing powerhouse, with the 480M's 897 gigaflops comfortably dwarfing its predecessor's 413 and promising almighty tessellation performance. What it all means with regard to keeping your frame rates up while traversing the Terminus Systems, we can't yet say. We'll let the benchmarking gurus figure it out -- go past the break for the full press release and spec sheet.
NVIDIA GTX 465 detailed ahead of June 1 launch, GTX 460 also rumored
Hey, you there, wanna check out some unreleased new hardware from NVIDIA? Donanimhaber, the same site that brought us early (and accurate) specs of the GTX 470 and 480, is back with the above shot of an ASUS-built GTX 465 that is intended to entice the more mainstream crowd into the Fermi party. Essentially a GF100 with its wingtips trimmed, this'll offer the same 607MHz graphics and 1,215MHz processor clock speeds of the 470, but comes with a narrower 256-bit memory interface, a tamer 3.2GHz effective memory clock, 352 rather than 448 CUDA cores, and -- happily -- lower power requirements. This word is also corroborated by Bit-tech, whose scribes expect a launch at the start of Computex. The Turkish site also has news of a GTX 460, which they say will show up in the middle of July with 768MB of GDDR5, while also being "cheaper and slower" than the 465. Hit the Hexus link below for some early benchmarks of the latter card.
NVIDIA GTX 480M will bring Fermi to laptops this June, crazy power requirements and all
We had an inkling NVIDIA wouldn't keep the Fermi goodness just to the desktop and here's our first pseudo-official confirmation. Rushing in ahead of any announcements, Eurocom has started listing a GeForce GTX 480M part, replete with 2GB of GDDR5 memory and a $345 markup relative to ATI's Mobility Radeon HD 5870. It's not clear whether the 100W number refers to the TDP or power requirements of NVIDIA's new GPU, but it's safe to expect both to be pretty high. The MXM 3.0b interface provides a 256-bit linkup between the GPU and CPU, lending plenty of bandwidth, but it also demands plenty of PCB real estate. As a result, Eurocom is offering the GTX 480M on its 17-inch Cheetah and Panther and 18.4-inch Leopard desktop replacements, but not on its 15.6-inch Cougar. Man, no love for the Cougars. According to the listing, we're only a month or so away from release. [Thanks, Jacob]
NVIDIA GeForce GTX 480 set up in 3-way SLI, tested against Radeon HD 5870 and 5970
Not many mortals will ever have to worry about choosing between a three-way GeForce GTX 480 SLI setup, an equally numerous Radeon HD 5870 array, or a dual-card HD 5970 monstrosity, but we know plenty of people would care about who the winner might be. Preliminary notes here include the fun facts that a 1 Kilowatt PSU provided insufficient power for NVIDIA's hardware, while the mighty Core i7-965 test bench CPU proved to be a bottleneck in some situations. Appropriately upgraded to a six-core Core i7-980X and a 1,200W power supply, the testers proceeded to carry out the sacred act of benchmarking the snot out of these superpowered rigs. We won't spoil the final results of the bar chart warfare here, but rest assured both camps score clear wins in particular games and circumstances. The source link shall reveal all.
NVIDIA unleashes GeForce GTX 480 and GTX 470 'tessellation monsters'
Let's get the hard data out of the way first: 480 CUDA cores, 700 MHz graphics and 1,401MHz processor clock speeds, plus 1.5GB of onboard GDDR5 memory running at 1,848MHz (for a 3.7GHz effective data rate). Those are the specs upon which Fermi is built, and those are the numbers that will seek to justify a $499 price tag and a spectacular 250W TDP. We attended a presentation by NVIDIA this afternoon, where the above GTX 480 and its lite version, the GTX 470, were detailed. The latter card will come with a humbler 1.2GB of memory plus 607MHz, 1,215MHz and 1,674MHz clocks, while dinging your wallet for $349 and straining your case's cooling with 215W of hotness. NVIDIA's first DirectX 11 parts are betting big on tessellation becoming the way games are rendered in the future, with the entire architecture being geared toward taking duties off the CPU and freeing up its cycles to deliver performance improvements elsewhere. This is perhaps no better evidenced than by the fact that both GTX models scored fewer 3DMarks than the Radeon HD 5870 and HD 5850 that they're competing against, but managed to deliver higher frame rates than their respective competitors in in-game benchmarks from NVIDIA. The final bit of major news here relates to SLI scaling, which is frankly remarkable. NVIDIA claims a consistent 90 percent performance improvement (over a single card) when running GTX 480s in tandem, which is as efficient as any multi-GPU setup we've yet seen. After the break you'll find a pair of tech demos and a roundup of the most cogent reviews.%Gallery-89115%
NVIDIA GeForce GTX 480 and 470 specs and pricing emerge
We're only a week away from their grand unveiling, but already we've got word of the specs for NVIDIA's high end GTX 480 and GTX 470 cards. Priced at $499, the 480 will offer 480 shader processors, a 384-bit interface to 1.5GB of onboard GDDR5 RAM, and clock speeds of 700MHz, 1,401MHz, and 1,848MHz for the core, shaders and memory, respectively. The 470 makes do with 446 SPs, slower clocks, and a 320-bit memory interface, but it's also priced at a more sensible $349. The TDPs of these cards are pretty spectacular too, with 225W for the junior model and 295W for the full-fat card. Sourced by VR Zone, these numbers are still unofficial, but they do look to mesh well with what we already know of the hardware, including a purported 5-10 percent benchmarking advantage for the GTX 480 over ATI's HD 5870. Whether the price and power premium is worth it will be up to you and the inevitable slew of reviews to decide. [Thanks, Sean]
NVIDIA GTX 480 makes benchmarking debut, matches ATI HD 5870 performance (video)
We're still not happy with NVIDIA's failure to publish anything on its site alerting users about the doom that may befall them if they switched to the 196.75 drivers, but the company's making an effort to get back into our good books with the first official video of its forthcoming GeForce GTX 480 and even a benchmark run against ATI's flagship single-GPU card, the HD 5870. It looks like you'll need to jack in a pair of auxiliary power connectors -- one 8-pin and one 6-pin -- to power the first Fermi card, as well as plenty of clearance in your case to accommodate its full length (stop giggling!). NVIDIA's benchmarking stressed the GTX 480's superior tesselation performance over the HD 5870, but it was level pegging between the two cards during the more conventional moments. It's all well and good being able to handle extreme amounts of tesselation, but it'll only matter to the end user if game designers use it as extensively as this benchmark did. As ever, wait for the real benchmarks (i.e. games) before deciding who wins, but we're slightly disappointed that NVIDIA's latest and greatest didn't just blow ATI's six-month old right out of the water. Benchmarking result awaits after the break, along with video of the new graphics card and a quick look at NVIDIA's 3D Vision Surround setup. Go fill your eyes.
NVIDIA's first two Fermi cards to be known as GeForce GTX 470 and GTX 480
Don't get too excited, we don't have specs or release windows yet, but we do have hilariously inflated model names to share with you. NVIDIA's all-new graphics architecture, commonly known as Fermi and recently re-coded as the GF100, has its first two commercial product names -- the GeForce GTX 470 and GTX 480 -- which as you'll have noticed skip right past the 300s and nearly double the model numbers of the company's current gen offerings. Let's just hope the performance lives up to such a blusterous naming scheme.
Nvidia details next graphics chip, codenamed 'GF100'
There's nothing quite like a 30-second tech demo clip to get our hearts racing. Maybe, just maybe, the inclusion of some steaming hot data to go with that footage, perhaps from a big PC hardware company like Nvidia regarding its next graphics chip. Good thing then that we have just that (we're shaking in anticipation just putting down these words), as Nvidia unveiled its "GF100" (a codename) alongside said video clip (embedded after the break) just recently. What about those pulse-pounding specifics, you say? Well, the chip features "3 billion transistors, double the CUDA cores of previous generation GPUs, a high speed GDDR5 memory interface, and full DirectX 11 support." Whoa, whoa, settle down there kiddo, there's more. Reports have gauged it as running games like FarCry 2 at 84.3 frames per second with the resolution cranked all the way up. No price has yet been given, but can you really put a price on quality? (The answer is yes, and it could be a high one.) [Via BigDownload]
NVIDIA Fermi / GF100 architectural details revealed
Fermi hardware might still be two months away, but NVIDIA has done the sage thing and released some tantalizing numbers and architectural details to keep the fanboys chirping in the meantime. The GF100 will signal the end of tiresome rebadging and clock speed massaging, and early adopters will find 512 CUDA cores, 48 ROPs, and a 384-bit GDDR5 memory interface sprawled across three billion transistors. Big changes are also afoot in how the card will do its work, with a reorganization toward a more parallel workflow leading to promises of up to eight times better geometry performance than on the GT200. HardOCP reports that anti-aliasing results have improved "notably," while the video we've got stashed after the break for you shows the GF100 beating the GTX 285 handily in a Far Cry 2 benchmark. Still, the PC Perspective crew expressed some apprehension about the massive die size and how it could impact yields given the still young 40nm production process -- a sentiment echoed by other publications who questioned whether NVIDIA would not have been better off trying for a less ambitious, more gaming-oriented board. We should all know that answer soon enough. Read - AnandTech Read - Hot Hardware Read - PC Perspective Read - HardOCP Read - Tom's Hardware
