標題: [硬件] 2012 iGPU Preview [打印本頁]

作者: qcmadness 時間: 2012-2-8 19:38 標題: 2012 iGPU Preview

1. Intel
HD4000/2500
Intel官方話HD4000快過HD3000 50-60%
主要係HD4000比較多shader (16 EU vs 12 EU, +33%)
仲有memory bandwidth (DDR3-1333 > DDR3-2133)
估計freq維持在1GHz左右

Intel升得咁快, 主要係因為呢樣野, 唔可以俾AMD爬頭
不過成本會幾好, 因為暫時收到4-core + HD4000的die size都只係大約160mm^2
2-core + HD2500應該會係100mm^2左右

2. AMD
HD76x0 / 75x0
AMD官方話HD76x0快30-50%
主要係shader增加 (80x5 > 96x4, + 10-20%) 同埋freq增加 (700MHz vs 600MHz, +15%)
效能唔會太差, 只係成本唔會低, 估計die size大約220-240mm^2

HD74x0
Brazos 2.0, 暫時無乜資料

3. NVIDIA
Tegra 3
所謂的4核皇牌, 新一年資料唔太多, 估計係Samsung, Ti出左A15 quad-core之後會打價格戰

歡迎補充

佢而家single channel DDR3-1333都食唔哂，升上DC 2133有鬼用咩

Intel係Graphic啲空頭支票仲勁過NV

(雖則HD3000叫過到最底線，不過K only

)

E3-1235 up are also HD3k.

some i3 also use HD3000

IVB追到A6，同50%增長預期相差不多

76Xx 220~240 mm^2. Qc你冇打錯ma?
大成咁不如出7770再cut cost 唔好?

24x係指成個APU package

Intel個4核重要減TDP,由95W降到77W.

AMD幾時跟住減TDP?

用緊65W4核啦喎

Not impossible with Ivy:

with 7750's 55W TDP.

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

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?

If you are referring to my post, they are System Consumption + Card Consumption for Max. loading.

Intel要用AMD可以唔洗用囉.

第一個表: System power consumption
Intel 65.3W
AMD 130.2W
第二個表: Display card max power
7750 47W
65.3W system + 47W display,何來額外HDD/Chipset/PSU呢?

Llano 65w gaming platform ~85w
Please subsidize me a 65w ivb+hd6570 for power consumption comparison
