Kaveri vs Richland - value for money

[NickC_UK]

Is AMD A10-7700 Kaveri worth the extra over a A8-6600 Richland? Price difference in the UK is £91 over £59 so only £32 different which is not a lot in overall build cost.

Depends what you want to use it for. Do you want to use the integrated graphics, or will you use a discrete graphics card?

(Also- where are you getting your CPUs? Cheapest price I've seen for a 6600 is >£70!)

If you can wait it out a bit, i'd go for the Kaveri A8-7600 that should be out sometime soon.

Much lower power consumption and very close to the 7700 in performance.

Cpu wise no it isn't worth it. We are talking about the A8 being 95 to 98% the same single thread performance of the A10 due to the fact actual clock speeds went down and the ipc barely went up enough to surpass the loss in clock speeds. Multi threaded the A8 is about 85 to 90% the performance of the A10, this is due to changes with steamroller that allow the cores to be better fed and there is less of a downside of CMT (amd's version of hyper threading which is very different than intel's version)

GPU wise yes it is worth it, but then again it is still it is a bad to decent gpu if your main purpose is gaming. (Once again AMD APUs are bandwidth limited for gaming). For internet browsing and office you do not need the extra gpu.

(The problem of apus in general, what is good enough graphics vs the cost to increase the graphics)

This isnt about the office build you have posted in your other thread is it?

Without a specific use case, I would be hesitant to recommend an APU at all. They are only a good choice if you need the best igp performance available, but are satisfied with less graphics performance than a low/mid level discrete card will give.

Richland should offer better value because it is older, however:

If you like overclocking I would go fo a10-7700

It should be quite a bit faster CPU wise than richland.

Overclocking improves igp gaming performance aswell:

Which makes it enough for 1980x1080 gaming. IMHO 1600x900 is prefered

If you dont care about the higher iGPU performance(both in gaming and GPGPU) then the A10-7700K is only a little faster than A8-6600K in CPU. It also has lower power consumption and higher dGPU performance than A8-6600K.

If you can spend the extra go for the A10-7700K.

And there is dualgraphics. Dunno how richland works in crossifre with dgpu, but kaveri scales nicely with cheapo r7 240

Also, does 7700k have TrueAudio?

 

[Torn Mind]

The A10 is not worth the premium since the discrepancy in CPU performance is small and the extra GPU compute power you are paying for will be wholly untapped. Your office rigs are better off if your workers can't install games on them.

Probably because I am looking at the net cost without Vat not the gross. Scan have the A8-660 for £58.65 net.

A10-7700K and 7850K have TrueAudio.

impossible to give good advice without the OP giving any clue to the intended use

so I'm going with the 6600, because hey, as a CPU it's probably as good as the other, and it's cheaper, on the IGP side both struggle to play newer games at high res (and low settings) anyway, but certainly the 7700K have a decent advantage in some games, it's just that the price difference looks significant enough, and if you are going to play games with the IGP is because you are trying to save money?

If it's an office PC and he's doing spreadsheets in LibreOffice, Kaveri will enable him to use the HSA Support.
