2 part question.

(First)

-R7 250 4gb gDDR3
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

vs

-R7 250 1gb gDDR5
http://www.tigerdirect.com/applications/searchtools/ite...

Which one will work better paired in Hybrid-Crossfire with an A10-7850k?

I am thinking that the crossfire may bottleneck the gDDR5 memory? Does crossfiring the r7 250 and running 1080 resolution better utilize the 4GB of ram?

(Second)

FX-8370 and r7-250
vs
A10-7850k and r7-250 in Hyrbid-Crossfire

which is better?

Which bottlenecks first, the CPU or GPU? Does an A10 CPU bottlneck high resolution gaming before a single GPU r7 250?

(ps. for future replies, please no alternative processors or graphics cards with similar price points... Im strictly interested in the questions surrounding these specific processor/card setups, for reasons including low-profile design and AMD-loyalty. No different options plz. :) )

The 1GB card by far. Don't waste money on GDDR3 cards at this point, and an R7-250 is nowhere near powerful enough to utilize 4GB. That size of VRAM on that card is a joke.

The FX-8350 far exceeds the A10

If you're gonna crossfire, I'd suggest looking into at least 2 GB cards if not higher.

The highest crossfire solution for the A10-7850k is the R7 250, and its only available in 1gb for DDR5...

So that said, which is better? A10-7850k crossfire with the 1GB DDR5 or with the 4GB DDR3? Since its crossfire, would it better utilize the entire 4GBs of DDR3? and would the crossfire slow the DDR5?

And not comparing simply an FX-8370 to an A10-7850k outright... but an FX-8370 w/ r7 250 vs A10-7850k w/ r7 250 in crossfire... Does the added crossfire performance with the A-10 make up for the processing when compared with the single-GPU performance in the FX? At r7 250 peformance levels, would the A10 processing really begin to bottleneck before the FX's single GPU??

Oh, if you meant to hybrid crossfire with the apu, then you'd probably want to go with a 7750.

You can use an hd7750 (best) R7 250 (worse) or r7 240 (most awful)

If price point matters, I'd still suggest going with the FX-8350. Get an R7-265, then an additional one later on for crossfire. And no, the 1GB card would still be superior in crossfire. Only at higher res would a difference be noted

7750 isnt available in a low-profile version, so its not an option. Beyond that, im not even sure if the 7750 crossfires with the A10-7850, I think thats only the a10-6800k right? Regardless, not a solution for what im looking for...

R7-265 is also not a solution, as its not available in low profile.

Also, the question is indeed for high-resolution gaming. Looking for 1080p gaming in modern titles at 30+fps, which I know the r7-250 and a10-7850k are capable of, but im trying to determine the optimal build for them...

Question is specifically for these builds, not for alternative options.

A10-7850k w/ r7-250 4GB DDR3 in crossfire
vs
A10-7850k w/ r7-250 1GB DDR5 in crossfire

and

FX-8370 w/ r7-250
vs
A10-7850k w/ r7-250 in crossfire

No other builds/options plz.

Thx for the info so far though. :)

Hard to get insight on these builds (also given alternative builds in the CPU forum, grrr) :( 

Anyone?

R7-250 paired with FX-8350 is superior mainly because you wouldn't experience much of a difference in performance with the hybrid crossfire. Crossfiring with a apu is completely pointless higher frames are acheived with an fx cpu and the same single gpu than crossfiring a gpu with an apu. Don't waste your money if that's what you're thinking of doing. An APU will not yield the same performance as a dedicated CPU and GPU. Ergo you should go with the much better FX-8350 in that scenario.

My explanation kind of makes the other question moot, but either way. GDDR5 > GDDR3

Im getting opposite opinions in the CPU section on the A10 vs FX thing.

The running theory is that r7-250 is the bottleneck in either build as a discrete card, so the FX's extra horsepower would be relatively mute unless encountering a CPU-intensive game... That said, with the r7-250 being the bottleneck, crossfiring it with the a10-7850ks IGP will yield beneficial gains for most games, as opposed to improving the processing power.

Most all research/reviews have shown crossfiring the 250 and the a10 will yield beneficial results over a discrete set-up, so unless the extra CPU power would yield comparable gains then the crossfire option is actually the better option.

Thoughts?

Yeah, although your questions were specific I still try to make suggestions with future in mind. Although you cant afford a dual discrete xfire right now, you may want to in the future, as both set ups youve highlighted will seem less than impressive soon if not immediately.

Skyrim for example would be widely more playable with the fx cpu set up. Although with the 1gb gddr5 you'll suffer a painful lack of vram death. Its still preferable overall. But if pure performance ovarall, right now, is the most imperative objective. Youd might want to go with the apu crossfire option for the reasons stated in the other thread.

Should make you most happy! For now... :p
