[TÓPICO DEDICADO] NAVI - próxima geração de GPUs da AMD

[Johnny Eldritch]

PSU manufacturer, Seasonic, has listed several unreleased AMD Radeon RX 7000 GPUs such as the 7990 XTX, 7950 XTX & 7950 XT.

“The unreleased GPUs were listed by Seasonic within its Wattage Calculator webpage where at least four new models are mentioned. Do keep in mind that AMD has so far not announced any new RX 7000 GPUs within its Radeon lineup though a potential refresh might make sense given the rumors surrounding the next-gen "RDNA 4" lineup being pushed back to 2025 and having no new high-end models in the GPU stack.

The same Seasonic "Wattage Calculator" portal also listed the Radeon RX 7900 XT, Radeon RX 7800 XT, and Radeon RX 7700 XT ahead of their official introduction. So either Seasonic knows something or these are just placeholders if AMD does potentially launch a refreshed family.

So coming to the GPUs, there are four new AMD Radeon RX 7000 GPUs listed which include the Radeon RX 7990 XTX, Radeon RX 7950 XTX, Radeon RX 7950 XT, Radeon RX 7700 Non-XT variant & the Radeon RX 7500 XT. It won't be the first time that AMD has offered a high-end refresh as the "XX50" models were introduced as an RDNA 2 refresh with 6950 XTX, 6750 XT, and 6650 XT. We should also mention that several unreleased GPUs such as the RX 7950 XTX, 7950 XT, and 7500 XT were also mentioned in ROCm 5.6 last year. The same pull request also features the 7800 XT, 7700 XT, and 7600 XT, all three of which have been launched.

Following is the full list of Radeon RX 7000 GPUs that have been disclosed but not officially announced or released yet:

> RX 7990 XTX
> RX 7950 XTX
> RX 7950 XT
> RX 7700
> RX 7500 XT

Now going back to what AMD had stated earlier, there aren't going to be any new RDNA 3 AISC's which means that Navi 31, Navi 32 and Navi 33 are the only GPUs within the family and all chips are derived from these three SKUs. All three chips have already seen their max core configurations being released on the desktop side with Navi 31's full config featured on the RX 7900 XTX, Navi 32's full config featured on the RX 7800 XT and Nav 33's full config featured on the RX 7600 XT. But so was with the RDNA 2 family but AMD still refreshed that lineup.

What we can expect from this potential AMD Radeon RX 7000 "RDNA 3" GPU refresh is higher clock speeds, higher power ratings, and the addition of faster memory. AMD has so far only used 20 Gbps on its Radeon RX 7000 lineup while NVIDIA has gone with 23 Gbps speeds.

Samsung has already been mass-producing 24 Gbps dies for a while and the company also introduced its GDDR6W memory back in 2022 which offers increased Densities & 64-bit DRAM so if AMD wants, they can use these solutions to further boost the performance of their existing lineup. Well, this is speculation from my end but let's wait and see if AMD would refresh its high-end RDNA 3 GPU stack or leave it like it is right now.”

Nvidia já batendo na porta c/ as 5000's e só agr a AMD vem c/ esses requentamentos.....................

.

Se esse rumor se confirmar, serão apenas “refritos” mesmo... e nada de inovação frente a(s) sua(s) concorrente(s).

Se esses “requentos” vierem num bom preço e tiverem melhorias significativas, até que podem valer a pena (pra quem está com RX 5000/Vegas ou anteriores, ou RTX 2000/1000 ou anteriores).

Eu, por exemplo, desisti de pegar a RX 7900 XTX (modelo Red Devil da PowerColor) e resolvi esperar pela próxima RDNA (3 ou 4) com o mesmo desempenho do que ela, só que consumindo menos energia, sendo menor, mais leve, com melhorias em Ray Tracing e por um preço razoável (até 7k pilas).

Em 2025 saberemos (após os anúncios oficiais), e decido se invisto numa nova Radeon (pra jogar em 4k +75FPS) ou se volto pra Nvidia (RTX 5070 / RTX 5080).

Mas se vier a preços baixos, são bem vindos.

Testei e achei bonito os efeitos de RT no The Witcher 3 e no Cyberpunk 2077, e de poder usar o DLSS (modo qualidade) e o gerador de quadros, via o mod DLSS ENABLER (usando uma RX 6800 XT).

Na Nvidia, o suporte a essas tecnologias é nativo (nas RTX 4000). Seria bom se AMD trouxesse melhorias no RT, nas próximas RDNA. O FSR 3.1 e o gerador de quadros já são promissores (ficou uma maravilha no Ghost of Tsushima).

Eu testei esse mod no CP2077 tbm na 6650xt. Só fiquei com uma dúvida. Se eu ativo o DLAA com o mod, seria o mesmo que jogar com algo tipo TAA?

Esses requentamentos deveriam ter sido lançados até o final do ano passado (pra ter algum resultado imo), e por ex. a 7900 GRE idem já no mercado ocidental pra competir c/ a 4070 S c/ antecedência. Qnd a 4070 S fosse lançada, era só a AMD reduzir os preços. Mas, como a AMD no time dessas respostas, aí nem adianta mto.........

Sei lá, lançar a essa hr qnd as 5xxx tão "saindo do forno", não acho q adiantará mta coisa.
