so I am trying to build my htpc, silence is key for me.

the i3 3225 ivy bridge + asus Radeon HD 7750 1G DC Silent

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

or

A10 trinity with the onboard graphics 7660


I am confused here, seems like the Gpus are the same?

so it will cost me 150 dollars more if I go with discrete card and i3.. for the same benefits?

graphics cards are double the price where I live so it's crazy

A10 costs 140 bucks
i3 csts 150 bucks

and the gpu costs 140 bucks.

I don't mind spending the money , only if it's required.

playing on a 50" plasma, watching 1080 ,blurays, and playing some games, skyrim (not to fussed on the settings, but should still look nice and move smooth enough, I wouldn't be playing it much just I want the option if I want to. but still enjoy the experience.

get the i3+7750.
an A10 does not make it a good choice for htpc when an i3 consumes much less power while giving much more performance for skyrim etc

if you want to play skyrim you might need to get the 7750. if you are just watching tv and movies the A10 should be fine

Skyrim is somewhat of an enigma. It’s not a very graphically-demanding game, but it does express a propensity for fast processors. We’re only using the Medium quality preset here. But it’s really only at 1280x720 where the game is smooth enough to be considered playable—and that’s only counting the two higher-end Trinity-based APUs.

less power? but there will be a dedicated gpu so that would consume more power wouldn't it?

also arent the cards identical in performance?

yes with the 7750 the power draw would become identical but you will obtain much higher performance because 7750 is 30-40% more powerful than 7660D graphics

30 to 40% more? that's a slight stretch isn't ?

The integrate Radeon HD 7660D is vastly inferior to the Radeon HD 7750. The performance difference is much more than 40%. The Radeon HD 7660D is weaker than a desktop Radeon HD 6570. The Radeon HD 7750 is basically equal to a Radeon HD 6770.

See link below for benchmarks vs the Radeon HD 6570.

NO the 7660D is not weaker than the 6570. its actually on par with the radeon 6670 ddr3 which is roughly 40-50% weaker than the 7750 which in turn makes the 7750 40-50% more powerful than 7660D.

Always go for discrete GPU rather than on-board graphics!!
For a 50" Plasma, i would recommend you HD7770.

The size of the screen makes no difference - it's still 1920 pixels by 1080 pixels.

What does make a difference - your RAMs:


This would be before cranking the APU graphics engine ... likely beyond 125% if you were so inclined.

If silence is key, buy the Trinity APU and slap water cooling on it.

No.

If you bothered to look at the Xbitlabs review I linked in my 1st post you will see that the Radeon HD 7660D performs worse than the Radeon HD 6570.

Below is another review from Rage3D.com which basically compares the A10-5800k (Radeon HD 7660D) vs. the A10-5800k DG (Radeon HD 7660D + Radeon HD 6670 dual graphics), Core i3 + Radeon HD 6670 and lastly Core i7 + Radeon HD 6670. There are other configurations though.

http://www.rage3d.com/reviews/fusion/amd_a10_5800k_laun...

As can be seen, the A10-5800k performs worse than the A10-5800 DG, Core i3 + Radeon HD 6670 and Core i7 + Radeon HD 6670. The exception is Civilization V were all four provides similar performance. However, the A10-5800k DG does perform well.

If you continue to insist that the integrated Radeon HD 7660D is as as good as a Radeon HD 6670 w/ DDR3 RAM (probably about 10% slower than w/ DDR5 RAM), then you should back it up with some benchmarks.

ok so i tried to search for proof of 7660D is equal to 6670 ddr3 but i could not find any. so i have to concede you are right. the 7660D is indeed performs on par to a 6570 :o  . but seriously i heard a lot of stuff about how 7660D is very powerful and how it compares to a 6670 ddr3 etc. :sweat:  if it indeed is on par with a 6570 then amd apu's are just not a viable gaming option for budget gamers at all when one can get a cheap pentium and a 7750 for same price and get twice the graphics power . whatever little respect i had for trinity is now gone as its no longer an option for even budget gamers. thanks for enlightning me and i wont recommend a trinity build for any budget gamer henceforth when intel can provide twice the performance at same price.
but i really hope that the next gen amd apu kaveri has a radeon 7750 level discrete graphics in the top model , 6670 for mid range and 6570 for entry level models. :)
