65W vs 100W APU - Page 3

post #21 of 24
If you go with the A8-6600K, you' have to put a ~$20 cooler on it if you want it to run reasonably quiet. By then, you're into the price range of an i3-4130 or A8-7600, either of which can run on stock coolers a bit more pleasantly, and both of which have noteworthy advantages, either in compute performance (i3) or GPU (A8-7600).

Current pricing: (at the time of this posting)
A8-6600K: $100
A10-5800K: $100
A8-7600: $110
i3-4150: $117

I can't come up with any way to rationalize a 100W A8-6600K given current pricing on these other options.

A few weeks ago, the 6600K was a value leader at $90 for builds that could use more GPU muscle than an i3. Today, it looks like a waste at $100 compared to the alternatives.

The price difference, in the UK at least, are larger than that between the two processors and would be cheaper for a cooler+6600K. I originally looked at the A8 7600 on one website though on Amazon it was significantly cheaper so, providing it stays at that price, its likely the one I will grab. The recycled RAM is 4x2GB, which is a problem for budget Intel boards on the H81 chipset since most have only two physical slots. If I got a i3, I could only afford a H81 board which then means I could only have 4GB of RAM letting the other 4GB go to waste.

APUs on the other hand let me just squeeze in a quad core with a motherboard that allows 4 RAM sticks while offering a bit better graphical performance. The user is unlikely to notice a difference between a AMD or Intel however, I would imagine they would see greater benefit from having better integrated graphics.

But thank you MrPerforations and mdocod, I was not aware they would need a cooler to stay within reasonable noise levels so will add that to my list.

Keep in mind that core count is not a measure of compute performance. The i3-4130 will handily out-perform any A8 in compute intensive workloads with its 2 cores. If you observe execution resources per core this makes more sense. A Haswell core has like twice the execution resources of a piledriver core and many other technological advantages. Obviously, the iGPU in the 7600 like 2-4X the performance of the i3 so that can be a more important factor for games where these iGPUs are all pretty much the bottleneck at any desirable resolution.

Sorry I missed the location. Saw some USA newegg links being posted and jumped to conclusions. Though I would offer that there are some great quality B85 boards with 4 RAM slots that aren't too expensive.

I realize you're probably eyeing some <£40 motherboards for the FM2 option. I don't think I would put a 100W APU on one of those bare-minimum motherboards. The 7600 would be a better candidate to run one of those uber cheap boards than the 6600K (or even the A8-6500). TDP ratings and real world power dissipation are not the same. A 65W A8-7600 Kaveri dissipates less than say, an A8-6500 when doing the same work. The i3 dissipates less than any of them under most circumstances, and the B85 board listed above is the only board I am aware of in this price class with VRM cooling on either of these platforms that meets the other requirements (size and slots).

Thanks! smile.gif
Having used that motherboard, I can tell you that it works fine, but the VRM's do get a bit toasty under load. I solved the problem (not that it really was one, but I wanted to make sure that it never was) by picking up a pack of tiny heatsinks for a few bucks on eBay: http://www.ebay.com/itm/301174227656?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

If gaming is any consideration and you're going the APU route, go for the 6800K at the very least, and you may want to seriously consider the 7850K. Those have the equivalent of AMD 6670 and 7750 GPU's, respectively, and are the only APU's that have any chance of giving you a decent gaming experience on any games from the last five years. The cheaper APU's still have better iGPU's than comparable Intel offerings, but that's like saying AMD's trash doesn't stink nearly as bad as Intel's trash. Neither one would offer any kind of decent gaming.

An Intel i3 plus dedicated GPU would, of course, perform better, but it would also cost more.
