Athlon X4 750k (Virgo) vs 760k (Richland)

post #1 of 4
Thread Starter 
My AMD knowledge is a bit rusty so I was hoping that you guys could share some light into this. Both are pretty much the same price, I understand AMD just released the Richland APU's but I couldn't find any info regarding the Athlon X4 760K.

Performance wise which is better? If you could point me to a review of the 760K that would be brilliant.

Look forward to your comments. Thanks.

Note: I know that the clock speed and turbo frequency is different, but if both were clocked the same which would be better?

There still aren't any reviews of that particular model, but from this Richland AMD A10-6800K and A10-6700 review I read a few hours ago the Richland part may overclock better. They got 4.73 Ghz stable out of the A10-6800K, so that is a good sign.

Architecturally the chips are the same, save for the better Turbo Core, where it is supposed to keep the APU / CPU at higher than stock speeds 25% more time, for example, the review says that the APU spends most of the time at 4.2 - 4.3 Ghz on all cores, and downclocks under continuous heavy load a lot less than Trinity, down to 3.8 Ghz this time.

Quote:
According to AMD, Turbo Core functionality has been much improved for Richland. One improvement is the addition of more voltage and frequency levels (operating points) so the integrated micro-controller can better choose performance for a certain workload, theoretically improving efficiency. The Turbo Core algorithms are also now able to detect when parts of the APU are bottlenecked and establish whether providing extra power will actually be beneficial. Finally, data from the new on-die temperature sensors around the CPU and GPU cores is also used to improve the accuracy of the power-based temperature calculations that the previous generation relied on.

The Athlon X4 760K has a Turbo of 4.1 Ghz, so it might spend more time at, say, 4 Ghz with all cores working (or even the full 4.1 Ghz since there is no GPU to account for) than the 750K which has the max. Turbo at 4 Ghz, which should more likely be possible when not all cores are being used.

But the best thing is really the potential for higher overclocks. Let's hope some review comes out and confirms if it does as well as the A10-6800K or not.

I'am all so trying to decide between the two and I have made my choice to go for the 760k as it overclocks a lot higher then 750k.

750k max out stable OC w/ air cooler is 4.4-4.5GHz and for the 760k is @ 4.6-4.8GHz, all bet it can hit 5GHz w/ good air cooling. w/ water ho knows what the limit is... wink.gif
