A8-3800 already 65W

Bulldozer 8C + A8可以嗎?

can < 100W full load?

Not impossible with Ivy:

with 7750's 55W TDP.

This is not a gaming scenario

Both tests were in full load, anything else can matter?

CPU + GPU Full load together != just add up

Simply wonder what else.

還有 我比較有興趣係

Intel iGPU 個part 似乎因為 設計分別 , iGPU 無記錯係有Memory Bandwidth 優先權
DDR3-1333 -> DDR3-2133 推高左 究竟會有咩幫助

AMD 我唔肯定有無  但係 > DDR3-1600 Dual Channel 再上都無咩大效能提升

Test過, A8的gaming power consumption同齋cpu load差唔多 (see a8-3850 bench)
而且要Intel的graphics performance追到APU, 就要插卡

No, my concern is if there are two tests showing their respective full load consumption,
1+1>2?
With the fact "A8的gaming power consumption同齋cpu load差唔多", it means CPU is not under Full Load when gaming and the overall power consumption of i3+7750 in game can even be lower as the proposed above.

1+1 < 2

but you have to consider that if you want some gaming WITHOUT a display card or using a low-to-mid-range card
you probably use more electricity than an APU or scarify a lot of performance.

if you need to use hd7750, than you would consider a K10 / bulldozer but not an APU

If you check on the Power Usage
1+1 isn't = 2

Even Intel one have "TDP Limiter" locked at ~65W

AMD APU have similar "feature" + C6 State to keep the max TDP below the hardware limit
(Plus it seems have hardware temp protection .....if APU reach certain temp will start throttling back )

65 + 47 = 112, still have 20W margin, even the PCI-E channel can push up the power consumption, can it be 20W much?
