I can do basic math just fine, though you seem to have failed to realize that there are more factors than you've considered at play here. You're assuming that the stream processors on the 4k and 5k series are the same. They're not. The 5k series supports more features on-die, and it seems some per-clock performance was sacrificed in order to make that happen.can you even do basic math? a 5870 with the SAME number of sp, tmus, and rops along with HIGHER clocks and NO crossfire to contend with losing to the 4870x2 makes sense?A current-gen single GPU card isn't as fast as a last-gen dual GPU card... makes sense to me.Too bad 5870 still loses to 4870x2.
Too bad that 4870x2 doesn't support DirectX 11![]()
You're also exaggerating the performance deficit. The HD5870 comes out ahead of the HD4870x2 in some benchmarks, and behind in others. Being a dual GPU card, the HD4870x2's performance relies upon crossfire scaling, which is hardly consistent across all games.
The HD5850 supports DirectX11, is better at DirectCompute, supports Eyefinity, supports DisplayPort, doesn't rely upon crossfire, and it does all this while consuming far less power than the HD4870x2. What does the HD4870x2 have going for it? It supports none of the above, and it's faster only sometimes.
The HD5870 might not always beat the HD4870x2 in every single benchmark, but it's a better design all-around. Like I said, it makes sense to me...
