[Rumour] ATI Cypress (Radeon 5800) Performance charts, Evergreen release dates/price information
A flurry of Cypress images have leaked today on the web. But here are some big ones – all originating from Chiphell and gathering.tweakers.net.
Leaked is an entire array of performance charts, comparing a 5870 vs. GTX 295, 5850 vs. GTX 285, etc.

Of course, these are unofficial, and should be taken with a grain of salt. The 5870 competes well with the dual-GPU GTX 295, ending up faster in most situations. The 5850 is 30% faster than GTX 285 on average, the current fastest single GPU product. A recurring pattern seems to be exceptional 8xAA performance for the Cypress GPUs. Also, it is interesting to note that the GTX 295 is actually faster in many of the lower resolutions, whereas at higher resolutions/extreme IQ, the 5870 is universally ahead. It may be a bit of a non-issue, as both cards are returning monster frame rates at those lower resolutions for most games. The 5850 beats the GTX 285 comfortably in each and every test, at every resolution, and in most situations with eye-popping deltas. Finally, we have a shoot-out between 2×5870 in Crossfire and 2xGTX 295 in Quad-SLI. The 5870 CF solution takes an easy victory across the board, aided by poor SLI scaling moving past 2 GPUs for the GTX 295. Here’s an interesting statistic – Crysis Warhead, 2560×1600, 4xAA, 8xAF, 42 fps. The 5870 CF figures also indicate where GT300 needs to be. A quick calculation suggests Nvidia requires about 2.5x GT200b (GTX 285) performance out of GT300 to compete with Hemlock. There are plenty of situations where the dual 5870 setup ends up three times as fast as GTX 285. Granted, Hemlock might end up downclocked to maintain a 300W TDP, this is also assuming Hemlock uses a straight Crossfire connector between the two Cypress dies.
Another interesting slide leaks ATI’s “Sweet Spot Strategy”. Cypress covers the area between $250 and $350. So far, the rumoured $299/$399 price points have been based on the assumption of <$400 for the HD 5870. It is quite possible that the 1GB versions of 5850/5870 will end up at $249 and $349, respectively, with the 2GB HD 5870 “Eyefinity/SIX” version at $399. Also, it doesn’t seem like a “bottom-to-top” generation launch after all. The HD 5800 series releases on 23rd September, “Hemlock” dual-Cypress and “Juniper” (HD 5700 series) around the same time frame in October, at maximum price points of $499 and $199 respectively. The entry level Redwood and Cedar only come in Q1 2010, which may explain the lack of any details. Once again, this slide is unofficial and could easily have been doctored, so only time will tell.
