用緊1440P 21:9 MON
用1700係咪好過i7
睇你要幾多fps
60fps 1700 ok
resolution 特效愈高 對顯示卡負擔愈大 fps就愈低 咁既情況 ryzen 既弱勢就愈唔明顯
我冇理幾多fps ..但只係想要耐用u應該買邊個好 同埋我ddr4 ram用唔用得番
耐用 1700吧
散熱好D 8核比較future proof
DDR4 RAM用得返 唔係3200mhz+的話
其實有無需要用3200mhz ram?
有
但ryzen行29XX算啦 廢事煩
點解? 求解釋

記憶體頻寬同CCX Data Fabric速度掛勾
Ryzen FPS不如Intel原因在於CCX, 令L3 latency太高
超一超RAM, 打機FPS會高唔少
RYZEN + 3600MHZ RAM - closing the 7700K gap in gaming?

#31有片, 有1700X配2133, 3200同3600, 以及對比7700K 5G配3200MHz
差距大幅拉近, 小部分game FPS甚至反超

所有ryzen都係, 只要有CCX, 要配合高頻RAM先至發揮倒威力
(當然係計effective bandwidth, 即係CL值唔可太高之類)
尤其配新嘅N卡, N卡依家用driver去令CPU做倒多工, 會不停用到L3, 2組核心之間唔夠快, FPS就唔會高
諗起早排呢度嘅"數字兄"話, 谷RAM頻率可以提升FPS
佢又大致講得岩, 不過唔止GAME受惠, 逢親多工應用都有著數

我睇的網反而叫大家RAM盡量拉高頻,就算timing好鬆都冇所謂,雖然自己會盡量拉緊
Higher Speed Mhz with loose timings ( example - DDR4-2933 at 16-16-16-34 ) is always better than Lower Speeds Mhz and tight timings ( example - DDR4-2666 at 14-14-14-32 ) as the data infinity fabric and north bridge benefits the most from higher Mhz. The higher the memory Clocks Speeds/Mhz the better it is for the system performance overall. So , shoot for the highest memory clocks you can get , even if it means using more relaxed timings.

我諗data infinity fabric (例如跨ccx 通訊)同埋北橋真係食bandwidth 多過食latency, 話哂會影響吞吐量, 反而差果幾ns未必爭太遠

或者同埋去到果個頻率, 延時增加個影響仍然未足以蓋過頻寬提升個效益
