Guys from techPowerUp have just posted a full set of benchmark results from a mysterious contributor.
A person using a controversial nickname — Great Kim — shared some benchmarks of his R9 290X sample. Apparently the GPU-Z entry with 800 MHz core clock was correct. Even the 4.5 GHz Effective memory clock seems to be confirmed.
TPU also confirm that the card is using 4GB memory across 512-bit interface. For that reason we can’t say that the memory clock is real, since AMD already told us that the R9 290X will use 300+ GB/s bandwidth, whereas the 4.5 GHz only results in 288 GB/s (although it should be a great starting point for future overclocking).
In terms of performance we surely have a counterpart to GTX TITAN. Depending on the game, you either have better framerate on 290X or the TITAN. Mostly though 290X wins with anti-aliasing enabled, which is showing a real power of more GPU cores. The ‘test’ includes most of AMD-picked titles, not to mention we have absolutely zero confirmation that these results are even real. So I wouldn’t even make my opinion based on these.
Radeon R9 290X will be available later this month. AIB partners don’t even have the cards yet, so don’t expect any custom models to be leaked sooner than that.
