Each of these clusters is sent instructions via two sequencers and arbiters inside the chip’s Ultra Threaded Dispatch processor.
Those 390 million transistors amount to 120 stream processors split down into 24 five-way superscalar shader processors that are split into three SIMDs, each with eight shader processors per cluster. The card uses AMD’s RV630 graphics chip, which has around 390 million transistors manufactured using a TSMC 65nm process. Over the years, we’ve looked at quite a few IceQ cards, and generally speaking the technology doesn’t change – why change a winning formula?īefore we move onto the card itself, it’s probably worth having a quick recap over what the Radeon HD 2600 XT is all about. Cards that use these coolers fall into the company’s IceQ series.

The company’s Turbo series is a range dedicated to offering slightly higher than standard clock speeds out of the box.Īdditionally, HIS moved away from ATI’s sometimes noisy reference design coolers and instead teamed up with the guys at Arctic Cooling to use its VGA Silencer coolers. We’ve been a fan of what HIS has done for quite some time, as it was the first ATI board partner to really break the mould of only offering cards clocked at ATI’s reference clocks. HIS Radeon HD 2600 XT IceQ Turbo GDDR3 Manufacturer: HIS So, without further ado, let’s have a look at how it gets on. Today we have one example under the spotlight – HIS’s Radeon HD 2600 XT IceQ Turbo GDDR3. At the same time though, AMD also recognises that its partners might want to make GDDR3 versions of the HD 2600 XT in order to make the cards more price-competitive with Nvidia’s GeForce 8600 GT. However, AMD is keen to push GDDR4 into the mainstream so that the price does eventually come down – this is something that Nvidia doesn’t seem to want to support. GDDR4 memory is expensive at the moment and therefore not suited to a mid-range card. To rub some more salt into the wounds, Nvidia’s GeForce 8600 GT showed more potential with anti-aliasing enabled and, for the most part, was a faster graphics card, but even that wasn’t a match for ATI’s Radeon X1950 Pro. You see, AMD’s previous mid-range product, the Radeon X1950 Pro, delivered much higher frame rates and therefore a better gaming experience when anti-aliasing was enabled. Last week, we looked at Sapphire’s Radeon HD 2600 XT GDDR4 graphics card, finding it to be very good on the features front, especially for HD video playback, but its real problem was that of value for money as a mid-range graphics card for gaming.
