Hello,

I have a couple of questions involving the A10-7850K APU.

1) Firstly, I would like to know if the Enermax ETS-T40-TB processor cooler will be able to handle an overclocked AMD A10-7850K. Its stock frequency is 3.70 GHz, going up to 4.00 GHz turbo. I was looking for 4.50 GHz. Is this a possibility with this cooler?

2) Secondly, what would the performance gains be from stock frequency, using DDR3-1866 memory, against its current position in PassMark?

3) Lastly, originally the APU was purchased to take advantage of its powerful IGPU, while keeping the build cheap (no real gaming, Minecraft at the most, which it handles on full settings; 1080p just fine). However, now that GTA V has been announced for Windows, I'm intrigued into buying it and will therefore need a dedicated graphics card to go with the processor. I was thinking of the R9 270X by Gigabyte, however is the A10 going to cause bottlenecking in this respect?

The game is set for a Q4 release, so no official requirements have been unleashed as of yet. Game Debate has a rough estimate, with the R7 250 under the 'medium' category, and a 6970 under the 'recommended' category. I'm thinking the R9 270X is around a 7870 in terms of performance, but I'm more worried about the processor being a bottleneck? I mean, it is a powerful quad-core, but it's not the best and it doesn't have L3 cache like the more powerful chips.

Thanks.

the R9 270X will not bottleneck with most games but RTS might be a problem.

If RTS equates to 'real-time strategy', I don't play them. Literally, just Minecraft and GTA. I'm more of a productive person than a gamer.

Should the A10 handle the R9 270X without any bottlenecking? I know at least it won't work in Dual Graphics, but I won't use that for GTA V anyway.

1.) It is possible, but not guaranteed. The problem with AMD's APUs is that they use really bad TIM between the chip and the IHS. So on air cooling you reach a point where even with the best air cooler it just can't pull the heat away fast enough and the processor starts to throttle. I've got my 7850K under one of the AMD heatpipe coolers that came with an FX-6300, and I can not get it over 4.2GHz. Beyond 4.2GHz is needs more voltage and the extra clock speed and voltage cause the processor to start to throttle under load. The Enermax cooler is better than the cooler I'm using, so I'd say 4.4GHz will probably work for you, and maybe 4.5GHz.

2.) No idea, I don't use passmark.

3.) I don't think the 7850K at 4.2-4.5GHz would bottleneck a 270x in any noticeable way.

I don't know how graphically demanding GTA V will be, but unless you see yourself playing more graphically intensive games at 1080p than Minecraft, then perhaps you could save some money and look towards a GTX 750 Ti or lower. Just a suggestion so you're not spending too much money - if GTA V is quite graphically intensive, then by all means get the 270x.

In order:
That cooler is decent, you should have no trouble reaching 4.5ghz with that cooler but much further will be a bit of a gamble. I pushed an A10-7850k to 4.7 on a hyper 212 and temps are just fine on a friends rig even under passmark stress so I would assume that would be just fine on that cooler since its massive enough. Just be prepared to turn the fan speeds up!

You would gain a decent performance boost in passmark in in gaming, should not be night and day but you will notice a difference that's for sure.

An A10 7850k will not bottleneck even an R9 290 so you should be just fine with that especially overclocked. A 270X overclocked version with a good cooler will give you some very nice gaming performance overall.

As for GTA 5, that's still a mystery because it depends on what the game demands mostly seeing as how there are no recommended settings show yet. But just basing off of experience, you will probably get around high settings at 1080p with reasonable FPS. The R9 270X is essentially an HD 7870 as you said, so you should be just fine in the performance category and overclocking realm.

What PSU you are using or plan to use? That is also a important component to see if you can OC your CPU and add the discrete GPU.

The Hyper 212 was my original choice. It was at the last moment that I changed my mind and went with the ETS-T40-TB as the bearing is more reliable and the cooler is quieter when not at full speed (since I'm using a Fractal Design Define R4 case, quiet operation was a factor for the computer's primary tasks of web development and document creation).

As for GTA V, only Game Debate has an approximate idea of what the game will require, but until Rockstar gives details (I hope some are given soon), no one can be sure. Judging by the optimizations that MP3 had, I can only hope they will be as good for GTA V, and not like that abomination that was GTA IV.


What PSU you are using or plan to use? That is also a important component to see if you can OC your CPU and add the discrete GPU.
I have the EVGA SuperNOVA NEX750 (750 W, 80-PLUS Gold), and at least according to the PSU calculator here, I should be within range (using the A10-6800K, since the 7850K is lacking from the list).
