Sure, times might be tough at AMD, but that's not stopping the crew at ATI from gunning for NVIDIA's newest gear -- the company just announced the new HD Radeon 4850 X2 and 4870 X2. Aimed at the "super high-end" of the market, the $399 4850 X2 and $599 4870 X2 feature two GPU chips on a 625 or 750MHz bus, respectively, with up to 2GB of 900MHz GDDR5 RAM. ATI says that there's a 20 percent overhead from pairing up the processors, so the X2s should offer 180 percent of the single GPU cards -- certainly enough to outgun a single NVIDIA GTX 280, and reportedly enough to match a dual-280 setup depending on the game. We'll see for sure when the inevitable flood of benchmarks hits when these bad boys arrive next month -- any gamers out there going to take the plunge?

Remember how we all swooned over Diamond's ATI Radeon HD 2900 XT in June of last year? At the time, that was pretty much your only shot at seeing 1GB of memory on a single graphics card. Fast forward to now, and we've got what's widely believe to be this planet's very first 2GB card. The PowerColor PCS HD4850, which is based on the RV770 core, comes with 800 stream processors and two whole gigabytes of GDDR3 memory. And just think, next summer you'll be sticking your nose up to find GPUs emerging with "only" this much memory. So fickle, we are.

Eran Badit of NGOHQ.com has already made some considerable progress getting PhysX to run on AMD hardware, and it looks like he's now getting a helping hand from a somewhat unexpected source, with NVIDIA itself reportedly giving the project its blessing. Apparently, NVIDIA has even gone so far as to invite Badit to join its developer program, which gives him access to documentation, SDKs and, most importantly, direct access to hardware and NVIDIA engineers, a move that Badit describes as "impressive, inspiring and motivating." Badit is decidedly less impressed by AMD, however, which has apparently been unwilling to provide with any hardware or support for the project. That stubborn stance, he surmises, can only be due to AMD's backing of Intel's Havok physics engine, which NVIDIA would no doubt like to have out of the picture (hence its willingness to help here).

Is this the Radeon card destined to leapfrog NVIDIA's performance leading GTX 200 series? We'll know in August (or soon thereafter), that's the rumored release date for AMD's Radeon HD 4870 X2 graphics card. As the X2 name implies, the card packs a pair of RV770-based GPUs and should be ready to sample with 2GB (!) of that "world's fastest" GDDR5 memory by the end of this month. It's worth noting that the leaked images show a total of 1GB of GDDR5 (16 Qimonda GDDR5 chips) on that black PCB. AMD will then make the 4870 X2 (RV770XT) cards available to its partners in mid-August, hitting retail soon after for an estimated $499 according to sources over at DigiTimes.

Just five days after ATI fessed up with an official release of its Radeon HD 4850, along comes a similar announcement for the just-leaked Radeon HD 4870. This dual-slot beast is finally being outed on the record, and at the very least, Diamond Multimedia's version will come stocked with 512MB of DDR5 memory, a clock speed of 725 MHz, 900MHz memory speed and 800 stream processors. The unit also provides CrossFireX upgradeability and should be available here soon from your favorite online retailer.

Considering that we've already seen AMD's ATI Radeon HD 4850 benchmarked, it's not like we really needed some official verbiage to cement our belief that the unit was real. Nevertheless, said verbiage certainly doesn't hurt, and that's precisely what's been delivered this morning. The HD 4850 is a single-slot PCIe 2.0 card featuring 512MB of DDR3 RAM, a 625MHz clock speed, 993MHz memory speed, 480 stream processors and support for CrossFireX / DirectX 10.1. We're also told that at least Diamond Multimedia's HD 4850 is available as we speak from a number of fine retailers, thus we presume everyone else's version of the card shouldn't be too far behind.

Judging by the fact that AMD tipped the whole world off to its upcoming RV770-based GPUs earlier this week, we don't suppose it'll be too upset that a 512MB MSI Radeon HD 4850 happened to land a little early in the PC Perspective labs. Design wise, there's nothing too out of the ordinary -- a single-slot cooler design, twin dual-link DVI ports, single 6-pin PCIe power connector and one goofy looking monster that you'll never see again once this thing gets installed. Care to see how it fared when facing the pressures of modern day gaming? You know where to look.

Hey Mac users, tired of looking longingly at that PC-lovin' ATI Radeon HD 3870? AMD has teased you long enough, and at long last, the Mac & PC Edition has arrived. This card is optimized for use within Apple's Mac Pro systems and includes 512MB of GDDR4 RAM, 320 stream processors, PCI Express 2.0 support and twin dual-link DVI ports for treating that pair of 30-inch Cinema HD displays like they ought to be treated. Check the read link for the full list of specifications, and get set to drop $129 when this one lands later this month.

AMD's on a roll at Computex, and it's keeping the stream alive with two more decently important announcements. First off, the company is making the ATI Mobility Radeon HD 3800 official, which is said to "triple top-of-the-line graphics performance in comparison to the previous generation ATI Mobility Radeon GPUs." The unit also enables laptop makers to include CrossFireX technology for the first time, so yeah, there's that. Moving on, we've got the low down on its PowerXpress technology, which enables users to "double or triple the performance of the integrated graphics processor when plugged into a wall socket or extend their battery life by over an hour while on the go." In actuality, it's a variant of ATI Hybrid Graphics Technology for lappies, giving folks the option to switch between a Mobility Radeon HD 3400 series GPU and an integrated AMD M780G without the need for a reboot. If your eyebrows just perked up, you can snag said tech on select Fujitsu-Siemens machines right now. All the gory details are linked below -- enjoy!

A full six months after Samsung took the wraps off of GDDR5 memory, along comes word from AMD that the next-generation ATI Radeon graphics cards will boast said technology. Apparently AMD will be tapping Qimonda for its supply of GDDR5 modules, which should boost gaming performance as well as benefit stream processing, "where GPUs are applied to address complex, massively parallel calculations." As Hot Hardware points out, the release comes just weeks away from the rumored debut of the Radeon 4000 series, so if our deductive reasoning is sound, we'd surmise that the looming Radeon 4800 will indeed feature GDDR5.

NVIDIA had already heard enough about AMD's ATI Radeon 4800 series to bump up the launch date for its GeForce 9900 series cards, but TG Daily has now apparently turned up some more launch details for the mid-to-high-end cards, the first of which is reportedly now on track for a release in mid-June. That first card will be the Radeon 4850, codenamed "Makedon," which will boast 512 MB of GDDR3 memory, single-slot cooling, CrossFireX support, and a price tag between $189-$219. That'll be followed in July by a pair of Radeon 4870 cards (dubbed "Trojan"), with one boasting 512MB of GDDR5 memory and the other boasting a full 1024MB, the latter of which will come with a dual-slot cooler. Look for those to cost between costing between $249 and $279. The whole lot of them will also pack "game physics processing capability," along with 7.1 channel audio via HDMI support, DirectX 10.1 support, and, as you might have guessed, some pretty heavy power requirements, with a 450 watt power supply needed for a single card and 550 watts needed for a CrossFire setup.

Although most of the attention in the increasingly-competitive CPU market has been focused on Intel and newcomer NVIDIA lately, AMD's still in it to win it, and it looks like it's taking some bold moves. First up, the company says over 100 laptop designs based on the new Puma mobile platform are being developed for delivery in June, over twice as many as it's had in the past. AMD's touting Puma's Hybrid Graphics mode that allows the system to intelligently switch between a Radeon HD3400 and integrated graphics for max power-savings, so it'll be interesting to see how the system stacks up against Intel's Atom and VIA's Isaiah -- like NVIDIA, AMD seems to be betting that consumers care more about graphics than raw horsepower.

That bet might also explain why AMD's technical director of sales and marketing Guiseppe Amato also recently told CustomPC that its next generation of chips will look "completely different" than Phenom, and that it will be capable of solving "problems that today we think can never be addressed by hardware." That's a pretty bold claim -- the whole processor market is getting pretty boastful lately, have you noticed? -- but we're at a loss to explain what it means. Any ideas?

Forget FPS and polygon crunching, we want one of these ASUS EAH3850 just for its sheer logic-defying properties. ASUS really took AMD's CrossFireX multi-GPU capabilities and ran with them, stuffing a ludicrous trio of GPUs onto a single "concept" card. Three RV670 cores power the setup, and it's kept cool by some heatpipes and a water block. If your box doesn't implode in incredulity, that means you can power four monitors with the three GPUs, or power a single monitor with all four at once for some seriously serious World of Warcraft, though we'll have to wait for benchmarks to see how well this setup actually runs.
