[操作疑難] x5650 workstation

如果而家用5千蚊多D砌部 x5650 x2 48 gb ram 既主機會唔會好傻豬?

你部機用咩software先?
software 會用到AVX嗎? (X5650無AVX)
software 食到2nd cpu嗎? (如Lightroom 只食一粒CPU)

留意Dual CPU 無得超,除非你買塊2手都要2千人仔的EVGA 神板

利申有 兩部workstation, 4790k @ 4.9GHz, 另一部dual L5639
兩部機跑分multithread 就差唔多
但用lightroom photoshop and etc 就好明顯係4790k快一點,因為大部份軟件 (render片的軟件除外)都係食到單CPU, 另外adobe 都有用AVX指令。

    多謝你回覆先
本時會用ae同埋 大量分頁上網
咁出機抵唔抵?

after effect not familiar, you better check if it uses AVX
If you plan on rendering video and browsing the web at the same time, it is good to have dual CPU.

you will suffer from poor single thread performance when working on the composition, but multi thread (rendering speed) is just on par with 4790k
do you really need that 48GB ram for your composition?

因為我估計ae render個時愈多ram會愈好
未必岩 只係再多既ram ae都可以食曬
有錯求指正

但係價錢上咁出花唔花算?

咁就一定有D傻豬架啦
用2637/2643 (v1 or v2)仲好啦

there are two scenarios here:
When you are doing the composition, because AE have to use ram to cache preview, so plenty of ram will help. But it's better if your GPU have Mercury Playback Engine support and massive VRAM, or else it struggles a lot for generating preview when you navigate across the timeline.

When you finish the job and submit to render, renderer cache the seq on the fly, not the whole seq at once. Ram became less a matter and raw processing power is the king. But x5650 is dated, power hogging and no faster than new i7, it is not so justified in long run.

If I were you I will rather invest on GPU for faster preview

guys, do remember it is DUAL X5650, multi thread performance should be better than overclocked i7. But X5650 single thread performance can be a huge problem.
And also X5650 motherboard has no SATA III.
If you taobxx, X5650 can be very cheap with motherboard, RAM, CPU and server power supply.
