ATI just announced its new mainstream graphics cards, the Radeon HD 4670 and 4650. At the heart of both cards is a 55nm 320-core TeraScale GPU, which is a modified version of the RV770 chip found in the Radeon HD 4800 series -- it's a lower spec chip, but it has essentially the exact same feature set. The $80 HD 4670 has 512MB of GDDR3 RAM, while the $60 HD 4650 uses 512MB of GDDR2 memory; both are relatively power-sipping with 60 watt and 50 watt draws respectively under full load. Should be out soon -- HotHardware just tested an HD 4670 and found it to be quite a performer, check it all out at the read links.

Loyal All-in-Wonder users from years past have probably been watching the progression of AMD's revised version of the card with extreme interest. After such an absence, however, we understand the need to be cautious before snapping this up for your upcoming HTPC. HotHardware recently received one of these units for testing, and while it was only deemed "entry level" in the gaming department, the multimedia performance was smiled upon. To quote, "the [card] did an excellent job presenting digital video content in a quality manner without creating excessive power consumption in order to do so." As expected, the unit wasn't recommend for everyone (read: non-TV buffs), but those who'd utilize the built-in ClearQAM support probably can't go wrong for $199. Hit the read link for a whole gaggle of test results.

Looks like all the Cinema 2.0 fuss that AMD has been blustering about with its new RV770-based GPUs is fully warranted. The benchmarks are in and AMD's new $549 ATI Radeon HD 4870 X2 -- what AMD calls the "world's fastest graphics card" -- is an out and out screamer, besting the best cooked up over at NVIDIA thanks to that RV770 GPU pair nuzzled up next to 2GB of GDDR5 memory. As noted by PC Perspective, the new champ, "is able to run away from NVIDIA's GeForce GTX 280 1GB card handily. Our various game tests proved this - Crysis, Call of Duty 4 and GRID showed big gains for AMD's new card at resolutions 2,048 x 1,536 and 2,560 x 1,600," though performance gains are less dramatic as resolutions drop to 1,600 x 1,200. Not that any self-respecting gamer would push so few pixels. CrossFireX performance was disappointing, however, as the systems didn't scale well when going from 2 to 4 GPUs. In fact, Crysis seemed to barely notice the additional CrossFireX horsepower, something that should be corrected with future driver releases. Make no mistake though, as power-hungry, expensive, and hot-running as the new HD 4870 X2 may be, it's a big day for AMD as it retakes the graphics crown from NVIDIA, as short-lived as this victory may be.

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?

In yet more news about the perpetually forthcoming Fusion CPU / GPU combos from AMD, new details have been leaked regarding the chips' sizes, configurations, and other bits of insufferably tedious details that only Professor Frink could truly love. According to this latest report, the "first" Fusion processor will be called "Shrike," sport a dual-core Phenom CPU, an ATI RV800 GPU, and a footprint of just 40nm. Another chip, codenamed "Falcon," will debut in 2010 at a 32nm size, based around a platform known as "Bulldozer," and will be launched to combat Intel's 32nm offering. Of course, we've been hearing about these chips since 2006, so we're not exactly on the edge of our seats hearing new details of what essentially amounts to vaporware.

While Intel's Larrabee might not be a household name for consumers just yet, it's certainly at the table where Nvidia and AMD/ATI eat. The many-core (8 to 48, at least, according to that Intel graphic) x86 chip runs all your existing apps while tossing in support for OpenGL and DirectX thus eliminating the need for a discrete graphics chip. At least that's the plan. While the exact number of cores remains a secret as does the performance of each core compared to current GPUs, given the importance Intel places on Larrabee, it's reasonable to assume that an 8-core chip will launch in 2009 or 2010 with comparable performance to GPUs on the market at that time. Intel does say that Larrabee cores will scale "almost linearly" (read: within 10%) in games; that means that a 16-core chip will offer nearly twice the performance of an 8-core chip, 32-cores twice that of 16, and so on. Apparently this has already been proven in-house with Intel name-dropping Larrabee-coded titles such as Gears of War, FEAR, and Half-Life 2, Episode 2. It's no coincidence then to hear that Intel's first Larrabee product will target PC gamers. Click through if you're just dying to read about Larrabee's 1024 bits-wide bi-directional ring network and other bits of technical wonderment sure to create at least the hint of a silicon malaise.

Well, no wonder Hector Ruiz quit as the CEO of AMD earlier today -- the chipmaker just announced its second quarter results, and they're not good. In addition to an overall $269M operating loss, the company is taking an $876M charge against the purchase of ATI so it can abandon the handheld graphics and digital TV markets. To be honest, we hadn't been hearing much about ATI's plans in those areas, so it's probably for the best the company is focusing on getting Barcelona out the door after the launch of Puma -- but we doubt much is going to happen with a power vacuum at the top and a bottom line that's bleeding red.

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).

An external graphics card that's actually nearing release? Be still our hearts! Fujitsu Siemens' recently leaked external unit, which will be based on ATI XGP technology, is actually really, really close to hitting retail -- according to a piece over at Fudzilla, anyway. Slated to be titled Lasso, the RV670-based device should be more than enough to handle basic tasks, but unfortunately, benchmarks were off limits. On the upside, digital photography was not, so head on down to the read link for a few more snaps.

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.
