Conclusions
Sapphire Toxic HD 5850 1GB GDDR5 is an excellent solution for overclockers. It bears a very efficient cooler which allows increasing clock rates up to those typical of Radeon HD 5870.
It was interesting to examine the effect of fewer stream processors, etc. Since Sapphire Toxic HD 5850 1GB GDDR5 worked at the core clock rate of Radeon HD 5870, and it also had the same bandwidth, the only difference was that it had fewer stream processors and TMUs. As you can see this didn't reduce card's performance much compared to Radeon HD 5870. Probably that's why Radeon HD 5850 has lower frequencies in the first place -- so the difference between the two solutions is more pronounced. Well, that and to increase the yield of ready products.
The example of Sapphire Toxic HD 5850 1GB GDDR5 proves that Radeon HD 5850 overclocks very well, given there's a decent cooler. In general, Sapphire made a very interesting product with a nice price/performance ratio. Of course, GeForce GTX 470 is faster at times, but it's also more expensive.
We express gratitude to Sapphire for the provided graphics card. The PSU is provided by TAGAN, the monitor is provided by NVIDIA.
