NVIDIA next-gen Ampere GPU on 7nm

Ultimele zvonuri despre arhitectura Ampere sugereaza o crestere de performanta "normala" (fara RT) intre 50% si 70%, plus o crestere de performanta in Ray Tracing intre 100% si 250%.

Daca pretul nu sare si el cu 50-70% (chestie normala ai spune tu) ramane de vazut. Chiar daca raman la aceleasi sume spun pass.

Mai ales ca aparent si scarlet si PS5 vor avea support pt RT (si foarte probabil jocurile vor fi mult mai optimizate) la o fractiune de pret.

Se intetesc zvonurile ca Nvidia Ampere ar putea fi cu 50% mai performanta decat Turing, cu un consum redus la jumatate. Asta inseamna ca se poate forta un spor de performanta si de 70% la un consum ceva mai redus decat generatia actuala.
Vestea proasta ar fi ca noile placi ar putea fi lansate doar la SIGGRAPH 2020, in august, deci ar putea fi disponibile in masa doar prin octombrie.

Am citit articolul ala si e f confuz.

Se afirma ca 50% perf ba la acelasi consum, ba ca la jumatate. In alta parte se afirma ca 50% in RT si nu e sigur daca e valabil global.

Oricum suna bine, sa vedem.

Ai citit alt articol mai vechi. In materialul pe care l-am citit mai recent e mentionat strict "pana la 50% spor de performanta la 50% din consumul generatiei actuale". Nimic in plus sau minus.
Oricum nu conteaza decat informativ.

Probabil e alt articol. Doar ca e nou. Si destul de varza:

https://www.tweaktown.com/news/69629/nvidia-ampere-gpu-50-faster-turing-half-power/index.html

"But this news of a 50% hike in performance at the same power consumption is big on its own."

" We could well see the '50% faster performance' in the ray tracing (RT) side of things, and not a general 50% performance improvement."

Cam sunt de acord cu afirmatiile de mai sus, nu prea cred ca vor avea 50% perf generala in plus la 50% consum. Dar, vedem. Daca lasa si preturile mai jos poate iau una. Daca nu ... s-ar putea sa dea rateuri la vanzari pt ca ... PS5 si xbox vor fi lansate anul asta.

"...new Ampere GPU architecture could be up to 50% faster, at half the power consumption of Turing."
Una este ce se poate si alceva este ce o sa ni se dea.  Nu cred ca primim mai mult de 30% pe partea de randare iar restul pana la 50% o sa-l primim de la refresh-ul seriei 3000.

Depinde de performanta AMD. Daca reusesc ceva similar cu ce au reusit in domenil procesoarelor, va fi nevoie de mai mult de 30% in plus la performanta generala pentru placile Nvidia.

AMD a iesit de mult din carti. Chiar si in articolul citat se vorbeste despre Ampere vs Turing, adica Nvidia vs Nvidia.

E clar ca nvidia marseaza pe RTX ... ei vor masura performanta raportat la RTX nu la raw processing power, sunt aproape convins ca vom vedea aceelasi spor de maxim 30% pentru seria high end, insa pe partea de ray tracing probabil x1.5 poate chiar x2

Inca odata sunt naiv si sper ca vom vedea DLSS 2.0 :)

Avansul in AI e in general foarte mare, deci e de asteptat ceva de genul DLSS 2.0. :)

AMD se lauda cu 100+% performanta la Navi 21 vs Navi 10, de unde rezulta ca doar 30% in plus performanta generala la Ampere nu ar fi destul cat sa mentina un avans rezonabil la varf.

Pai DXR este calcaiul lui Ahile al actualei generatii, este normal sa ridice performanta in ray-tracing.

...

De unde 100% daca trecerea de la 7nm la 7nm+ le asigura un spor de performanta de doar 15%?

Pai restul vine de la optimizarea arhitecturii plus numarul dublu de shading units fata de 5700XT.

NVIDIA Ampere GeForce RTX 3080 20 GB And RTX 3070 16 GB Graphics Cards Alleged Specifications Leak Out – Up To 3480 Cores, GA103 / GA104 GPUs

Am o banuiala ca nu vor lasa atat de multa memorie in ele, desi ar fi recomandat sa fie.

"It is clearly mentioned that Ampere would halve the power consumption compared to existing Turing GPUs. This means that a GPU with a lower TDP figure than the RTX 3060 (125-150W) would be able to outperform the 2080 Ti which is seriously impressive."

3060 peste 2080 Ti ar fi ceva prea tare. ;D
