doh.gif Yes he is, and I am bad at reading. I was, uh, multitasking? Yeah, that's a good defense... It's got 384 shaders, so it's a bit underpowered for DGM with Kaveri. I'll take a 7770, please.

no idea about the r7-240 or the basic r7-260... though i expect the 260 will be a 7770 rebrand.

R7-240 and R7-250 seem to be rebrand of HD 8570 (OEM) and HD 8670 (OEM) respectively.
http://en.wikipedia.org/wiki/Radeon_HD_8000_Series
http://en.wikipedia.org/wiki/AMD_Radeon_Rx_200_Series

Same Codename (Oland), (Oland Pro for 240 and Oland XT for 250)
Same die size (90mm^2),
same no transistors (1040m),
same SP to DP ratio (1:16),
R7-240 just has less 64 shaders and 8 TMUs than HD 8570. But 240 seems to be significantly more power efficient than 8570

HD 7730 is GCN 1.0. It is based on Cave Verde (Specific code name is "Cape Verde LE"), cut off version of Cave Verde Pro or HD 7750.
123mm^2 and 1500m transistors for HD 7730, HD 7750 and HD 7770.

Radeon R7 260 is Cave Verde PRX, seems to be a rebrand of 7770.

I think they're both closer to a 250, which is exactly the same other than clockspeeds and PCIe interface.

We'll have to see how dual graphics performs, but I think Kaveri Athlon ($90-100) + R7 260X ($150) would be an optimal budget config.kA7FwG

smile.gif Hey !
Does anyone have any idea of overclock-ability of CPU portion of A10-7850k ?
I mean, should it be able to do 4.9-5.0 GHz ?

lol lots of OCN members seem to be coming this thread under the impression of new Title tongue.gif

If they use the same voodoo magic as they did in Richland, then yeah, that's easily achievable. I didn't even notice the title change; I just check my subscriptions. tongue.gif

No way to gauge how the CPU or GPU portions will overclock as of now. There has been a small clock regression compared to Richland (the 7850k is clocked only 100mhz lower than the 5800k, however, not that huge) but since Kaveri is apparently on BULK rather than FD-SOI, supposedly it won't OC hugely. We'll have to wait and see for some reviews/testing.

I don't think BULK alone means low overclocking, supposedly Intel uses BULK as well.

If the voodoo magic comes true then I could replace my 8350 with A10-7850K at 4.8-5.0 GHz wubsmiley.gif
It should consume at least 100w less power than 8350 at 4.6 GHz mad.gif
As my system has been running at an average of 16.5 Hrs per day since 3 years, I might see significant reduction in power usage per month.

It might be tougher to overclock, but I don't think the process itself would hold back overclocking potential as much as the design of the CPU. They could've sacrificed some frequency for IPC, but I think AMD's stock clocks for the 7850K are a little on the conservative side (target CPU Base Frequency was 4GHz AFAIK).
