ATI RV740 Performance Figures Leaked





Benchmarks place it comfortably between the HD4830 and HD4850

Despite an uncharacteristically tight-lipped stance from ATI on its first 40nm parts, hardware review website Guru of 3D has managed to secure a sample of an RV740-based graphics card and put it through the paces. At first glance, the specifications suggest that it is little more than a shrunken RV770LE core, but a closer look reveals several improvements

According to the preview published today, the GPU boasts 640 shaders, 32 TMUs, and 16 ROPs; all the same as the RV770LE. However, the core and memory clocks both receive a significant bump, up from 575MHz to 650MHz and 1800MHz GDDR3 to 3200MHz GDDR5 respectively. The substantial boost in memory frequency works to offset the performance difference incurred by the smaller 128-bit memory bus on the RV740, which brings the reported math processing rate for the GPU up to 900 GigaFLOPS.

Every single benchmark result published in the review places the RV740-based card right between the existing Radeon HD4830 and HD4850 graphics cards, also from ATI. For example, at 8xMSAA and 16xAF in the popular first person shooter Left 4 Dead, the RV740 turns in 28 FPS, flanked by scores of 25 and 30FPS from the two cards at 2560x1600 resolution. The card does exhibit a significant performance drop at higher resolutions, likely the result of the 128-bit memory bus width and the relatively low 512MB of memory. Other reported benchmarks include Far Cry 2, Crysis WARHEAD, Call of Duty 5: World at War, Brothers in Arms: Hell’s Highway, and 3DMark Vantage.

MSRP for RV740-based graphics cards is expected to be $99 USD, which should make it a very attractive offering in the upper-mainstream segment. While the official name of the video card has not been released, the author of the article suspects it would be called the Radeon HD4750, which would be a logical name for a card with the given characteristics.

The Verdict

The economy right now is in a tight spot, the entire world is fighting off the global financial crisis. As such people will have less to spend on entertainment and niche products, that is where graphics card series like the ones shown today come in. This is one of the reasons why I believe ATI's RV740 products could be a nice success. Products like these offer very decent gaming performance targeted at the budget end-user below a 100 USD level. That's stuff to think about for a minute. I mean, for less than 100 bucks you'll be able to get a videocard that performs fairly close to a Radeon HD 4850. I think that's impressive, an achievement all by itself.

However we must use some caution here, these are preliminary results, done with beta drivers and an early engineering sample board.

But products like shown today always get me going and thinking. For example: think a step ahead in a little more enthusiast manner... what would happen if you place two of these cards in Crossfire in your system? That would get you into the high-end performance segment fairly easy... for under 200 USD.

So here's what you need to fillter out and realize... this product is performance wise, very similar to mid-range products we have already seen, but the pricing is exactly what would make this product grand. If anything, RV740 will be responsible for another shift in current mid-range pricing, and you guys will have AMD to thank for that. See, we expect to see the GeForce 9800 GT (=GeForce GTS 240) make a shift in price towards 100 USD once this RV740 is unleashed. And we expect the GTS 250 (9800 GTX+) to drop towards 150'ish USD. Yeah, interesting times are ahead of us you guys.

Other then that being said, I want to close this preview right here and now. The results you have seen were based on an early sample. Final specifications could even be a little higher yet, also lower with the final SKUs, but from a performance point of view, what you have seen will be the baseline set by this product, results cannot and will not be far off. And that's surely looking mighty fine for ATI.

As a mainstream part, it will be priced around $100, likely less, making it a super deal for gamers on a small budget. We can't wait to get our hands on the final product, to be released in the April timeframe.

Pelo preço nao tá mau. Quero ver é as placas que ultrapassem as hd4870 ou as novas da nvidia
