6800 xt 定 3080

3090 24GB ram, 玩deep fake 唔lag.

ps5 係rdna 2 based

無rt core
只係hardware accelerated rt by Gpu(cu)
無dedicated block (tensor core)

有rdna3 feature 係唔出奇 佢係custom rdna2
我又prove唔到有 你都prove唔到無 sony亦唔會講
信不信由你

我都同意冇RDNA3 啲嘢, 如果有歡迎貼link

RDNA2 黎緊仲會用落好多嘢度, Tesla Model S Plaid, Samsung Exynos
逐個HW feature-set 咁同佢數真係太攰
我會認知佢地係同一個GPU family 就夠

rdna 1 2都無rt core
蘇媽都話未來先考慮hardware rt
暫時佢地都係software rt

1 RA per CU

sor 太耐無追 如果連rt core都無
dllm咁就根本係rdna 1高cu加超頻啦
custom到個rdna2同rdna1無分別 Sony都算犀利
你岩 我無證據證明佢100%係rdna1 又證明唔到佢無rdna3嘅新feature 但係佢作為rdna2 眼見到閹割得最犀利就係佢 rdna3就發佈都無發佈過 我憑邏輯估佢無可能同rdna3有關係

簡單講PS5 GPU 有冇咩feature 係PC RDNA2 冇先？
UMA 就唔駛講喇, x86 open PC standard 好難推呢樣嘢

補充

Hardware Accelerated Raytracing
New to the AMD RDNA 2 compute unit is the implementation of a high-performance ray tracing acceleration architecture known as the Ray Accelerator. The Ray Accelerator is specialized hardware that handles the intersection of rays providing an order of magnitude increase in intersection performance compared to a software implementation.4

it's missing all the features related with DirectX12U along with mesh shaders but has the GE (Geometry Engine is Sony's custom solution that does the same job) and int4/8 support no ai acceleration. PS5 has another features not available in RDNA 2, the tempest engine.



上網抄

Sony's custom solution Geometry Engine
Sony's audio solution tempest engine
audio 都講咁不妨講埋Sony SSD 速度?
我唔覺Sony 會授權呢啲技術俾AMD 個RDNA3 當公厠咁俾晒全世界用
至少Sony 唔想因為咁益咗Xbox

我諗pc 版rdna 3 唔會用到sony engine
應該係用返dx 12/ vulkan api

咁唔叫醒目喎 主機市場大過diy咁多

薄利多銷
如果你仲想defend, 不妨諗下MS, Sony 同nVidia 高層呢個問題討論咗幾多次都係變改唔到目前結果

Nvidia擺明蠢左啦
主機市場比amd食曬 得翻switch
主機市場依家都係amd主要主場之一
相反diy根本唔入流

其實ok 既

你可以做management consultant 去advise nVidia management 應該點做
話俾佢地知自己點解錯, 同應該點改. that is...如果你做到同說服得到既話
或者至少你可以去股東大會發問同屌一屌nVidia 個決定

同理 你咪去笑下amd點解要接主機單囉
事實就係diy市場需求減少
專業應用需求又唔多
你估nvidia唔想接xbox同ps5單？
唔肯下放技術 成本又高
人地鬼睬你咩
Switch睇怕遲d都可能轉埋去amd

我覺得amd個個dlss唔可能做得好過nv

我的確唔想AMD 浪費精力資源去訂製主機ASIC 而全力同nVidia PC 對抗
所以我讚賞nVidia management 全力PC graphics 既決定

再討論落去會變咗PC graphics (包括專業卡) 出貨量幾多, revenue 幾多
console graphics royalty 同收入又幾多

Nintendo Switch 先最醒. nV 賣粒smartphone market 打輸又退出market 既Tegra SoC Nintendo 就搞掂. 教材級數既循環再用環保事業
作為nVidia 股東我真心鐘意佢呢一招

VRAM唔夠問題可以參考iphone 同Android

其實一明唔明vram比3080多咁多，但效能比佢高1成多啲係咩玩法

vram本身冇運算力

新手一問
其實有冇話amd一定配返amd cpu好d ？

Windows graphics API 面對仲咁多年嘅問題點參考？
