Why can't the CPU be clocked at 2GHz, 1.84TF count is for the GPU only.
Xbox GPU isn't a 7790, the 7790 has 896 Cores, it is somewhere between 7770 and 7790 but closer to the former rather than the latter.
Not sure how you figure that an overclocked 7790 (which the Xbox GPU isn't) is faster than 7850. The 7850 has 256-bit memory bus compared to 7790 128-bit, 7850 60% more memory bandwidth, 70% higher pixel rate, twice the number of ROPS. The 7790 is clocked at 1GHz vs 7850 850MHz but is still slower.
OK I go on rumours, but I don't make up stuff like you do about there being some magic extra logic that you are hoping might be there, or that Microsoft might have clocked the CPU/GPU faster than the PS4, I am going from the information that is out there.
I know E3 is about games, I was explaining to Draken why I won't be buying Xbox.
ok let me just say this now: I've seen you posted things which gave me the idea that you knew what you were talking about, but now I think I've changed my mind about that. I mean, you don't even know how they reached those teraflops numbers.
how do they reach the tflops? the ps4 has 1152 stream processors (GPU) and is running at 1.6ghz cpu speed: that's 1152x1.6 = 1.843tflops (single precision)
the xbox One has 768 stream processors (GPU) and is rumored to be running at 1.6ghz cpu speed: that's 768x1.6 = 1.23tflops (single precision)
that's how the TFLOPs numbers, the processor speed is accounted for. If I am wrong prove it.
quoting TFLOPs now a days doesn't really say much because it doesnt' take into account other things like GPU frequency, bandwidth, latency, architecture differences. therefore these TFLOPs numbers are more a ballpark figure if anything.
how do I know because I looked at the overclock reviews that's how I know an overclocked 7790 beats a 7850. Plus Sony 7850 is underclocked.
I also think sony might be having heat issues because they're using a lower gpu clock speed from 860mhz to 800mhz.
plus the 7850 uses amd's GCN v1 while the 7790 uses amd's GCN v1.1 (updated architecture remember tflops numbers doesn't take this into account).
the 7850 has a 150w TDP while the 7790 has an 85w TDP
GDDR5 runs much much hotter than DDR3 and uses much more power
The fast esram would take care of any bandwidth bottleneck. Also esram is way less power hungry than the edram used in the 360.
So far it seems the Xbox one should run much cooler and quieter than the ps4 and use way less power. Unless Microsoft changed the estimated clock speeds which would explain the large heatsink and fan.
