On the one hand, the 7870 gets quite close to the 7950 here in our AESEncryptDecrypt benchmark, in spite of the latter’s higher number of shaders. The results of this benchmark are the average time to encrypt the image over a number of iterations of the AES cypher. The only real competition here for AMD is AMD.įor our next benchmark we’re looking at AESEncryptDecrypt, an OpenCL AES encryption routine that AES encrypts/decrypts an 8K x 8K pixel square image file. SmallLuxGPU continues to showcase the 7800 series’ improvements over past AMD architectures, and while it’s not the same kind of massive leap we saw with CivV, it’s still enough to bring the 7850 up to near the performance of the 6970, and pushing the 7870 well beyond that. We’re now using a development build from the version 2.0 branch, and we’ve moved on to a more complex scene that hopefully will provide a greater challenge to our GPUs. Our next benchmark is SmallLuxGPU, the GPU ray tracing branch of the open source LuxRender renderer.
Compared to NVIDIA’s lineup the 7800 series does fairly well for itself too, although not quite as well as the commanding lead the 7900 series took. The Civ V compute shader benchmark once again shows off just how much the compute shader performance of the 7800 series has improved relative to the 6900 series, with both 7800 cards coming in well, well ahead of any previous generation AMD cards. Note that this is a DX11 DirectCompute benchmark. Civ V includes a sub-benchmark that exclusively tests the speed of their texture decompression algorithm by repeatedly decompressing the textures required for one of the game’s leader scenes. Our first compute benchmark comes from Civilization V, which uses DirectCompute to decompress textures on the fly. With GCN AMD significantly overhauled their architecture in order to improve compute performance, as their long-run initiatives rely on GPU compute performance becoming far more important than it is today.

Built on the 28 nm fabrication process, this new chip holds 2.8 billion transistors. The two are based on AMD's brand new GPU, codenamed "Pitcairn". The slide above is every indication of AMD trying to justify launch prices of $349 for the HD 7870 and $249 for the HD 7850, just because they are touted to outperform whatever NVIDIA currently has in those price-ranges (we're going to find that out in this review).ĪrchitectureThe Radeon HD 7800 series consists of two models, the Radeon HD 7870, and the Radeon HD 7850, both stretched far apart in the market segment. You may recollect AMD's Radeon HD 6870 shipping for $240 on launch, and the HD 6850 for $180, both very attractive prices. AMD kept the theme going with the Radeon HD 7800 series. The launch prices of Radeon HD 7900 series resembled those of NVIDIA's high-end GTX series, the Radeon HD 7700 series products ask a couple of dozen Dollars too many.
AMD appears to have exploited this late-coming by NVIDIA. NVIDIA hasn't even started with its next-generation GPU lineup, leaving its previous-generation to defend itself against a reinvigorated AMD lineup.
