AMD elevates the low-end with trio of sub-$100 cards: Radeon HD 6670, 6570, and 6450
Graphics card companies don't live and die by the enthusiast market alone. That may be where the glory is, but it's the budget cards that really bring in the bacon. For the entry level, AMD just unleashed a trio of sub-$100 cards, the Radeon HD 6670, 6570, and 6450. How do they perform? Well, let's just say you get what you pay for. Reaction from reviewers has been one of mild indifference. Depending on manufacturer, fan noise does appear to be an issue, possibly precluding the cards from being a viable HTPC choice. Otherwise, even the lowly, $55 6450 is a worthy upgrade over an integrated graphics chip or a two-year-old discrete card, but it can't match the performance of NVIDIA's GT 430, which can be had for only a few dollars more. Consensus was that, with prices of the older 5000 series being slashed, purchasers can get more bang for their GPU buck by sticking with last generation cards (like the Radeon HD 5750) if they're looking for pure gaming prowess. That said, the GDDR5 flavors of the 6670 provide perfectly playable performance on most modern games (it averaged 45 FPS in Call of Duty: Black Ops) for just $99 (the 6570 runs about $79). Just beware those models shipping with GDDR3. Benchmarks galore below.

AMD launches Radeon HD 6990 powerhouse for $699, maintains 'world's fastest' title
If you're scoring at home, NVIDIA currently holds the lead in single-GPU graphics cards with its GeForce GTX 580, but ATI's dual-chip Radeon HD 5970 has been holding down the absolute speed crown for a good long while. Now, bearing the name of AMD Radeon HD 6990, its successor sidles up to the throne and demands attention as the fastest single expansion board you can plug into your shiny new motherboard. The 6990 boasts a massive 4GB of GDDR5, 3,072 Stream Processors, 64 ROPs, and an 830MHz core clock speed. A dual-BIOS switch will let you crank that clock up to 880MHz with a corresponding increase in voltage, but don't expect to see much overclocking headroom above that. Reviewers note, alongside their fawning assessment of the world's best performance, that the HD 6990 is a massively power-hungry card (375W TDP) and one that makes quite a bit of noise while going through its herculean tasks. That's in spite of a new vapor chamber cooling system that allegedly supports up to 450W of thermal output. If all this strikes you as a somewhat flawed execution, maybe you'll join us in hoping NVIDIA's imminently upcoming response, dubbed the GTX 590, will be able to offer a neater, more efficient assault on the extreme peaks of graphical performance.

ATI busts out Radeon HD 5830, covers all bases
Whether you wanna call it the affordable high end or the really supercharged midrange, ATI has decided that there is a space to be filled between its scorching 5850/70 cards and the only somewhat slower 5770 SKU. So let's all meet the $239 HD 5830, shall we? As is par for the Evergreen course, it's a 40nm DirectX 11 card, and while it matches the 2.15 billion transistor count of the 5850, the new contender makes do with only 16 ROPs and 1,120 stream processors. To compensate for that processing loss, the core clock is raised to 800MHz while maintaining the 1GHz memory speed of the elder 5850. If this sounds like the 5830 will basically be composed of 5850 chips that didn't quite make the high grade, good, because that's exactly what's happening. Internet reviewers have already had some time to play around with ATI's latest card, and if we can draw a consensus, it would be that while the performance is pretty much spot on between its nearest siblings, the price is that little bit too steep to make the HD 5830 an easy recommendation.

Samsung begins production of 50nm GDDR5 memory
It's still a little ways away from actually landing in some graphics cards, but Samsung has announced that it has begun mass production of its new 50nm GDDR5 memory, which promises to support a maximum data transfer speed of 7.0 gigabits per second and boast a maximum bandwidth of 28 gigabytes per second. What's more, according to Samsung, the shift to a 50nm manufacturing process also increases production efficiency by a full 100 percent, and allows the memory to operate at 1.35 volts, which is a 20 percent reduction compared to current GDDR4 memory. From the looks of it, however, manufacturers will have to make do with a 32Megabit x 32 configuration (also configurable as a 64Mb x 16 device) initially, although Samsung says it plans to expand the 50nm process throughout its graphics memory line-up by the end of the year.[Thanks, Shattered Ice]
Next-generation ATI Radeon cards to pack GDDR5 memory
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.[Via Hot Hardware]
Samsung announces world's fastest memory: GDDR5
Gadzooks gamers, Samsung just announced what they are calling the world's fastest memory: GDDR5. The new series five, double-data rate memory chip transfers data at a lickity quick 6Gbps -- about 4x faster while using 20% less power than the GDDR3 memory found in modern GPUs and the PS3. Compare that to their 4Gbps GDDR4 chips and you'll understand the fuss. The chips have already been delivered in samples to the likes of NVIDIA and ATI. Samsung expects the series five chips to capture more than 50 percent of the high-end PC graphics market by 2010.[via DigiTimes]
