Se isto for verdade, o mercado vai continuar basicamente igual ao que temos agora, o que é uma pequena desilusão.

Nvidia’s GTX 980 Maxwell Slower Than GTX 780 Ti & 8GB Model Coming Later

All new GPU architectures are hyped before their release, but some more than others. The original GeForce, the Voodoo 5, the 9700 Pro… While some of those cards lived up to expectations, others (the Voodoo 5) just didn’t. Nvidia’s Maxwell is one of the most anticipated architectures in recent memory, but all signs show that the neither GeForce GTX 970 or even GTX 980 will have the performance to beat the Keplar based GTX 780 Ti.
Overclockers UK are one of the leading UK retailers for computer hardware, and one of their managers, Gibbo has posted a few very interesting comments on the OCUK forums.
“980 / 970 4GB reference cards with 8GB coming at a later date with custom coolers,” Gibbo began, confirming earlier rumors hinting that we’ll be seeing 8GB Maxwell models after launch. “Can’t say any more but don’t expect a huge leap in performance over current single GPU stuff.” he added.
Regarding the GPU’s performance, “They replace 780, not 780Ti,” said Gibbo, likely to the disappointment of many. “Performance wise, my lips are sealed on how it compares to 780Ti, but of course 980 is quicker than 780 for sure!”
So there we have it, pretty much confirming that if you’re the owner of the GTX 780 Ti, the R9 290X, Titan or Titan Black, and arguably the R9 290 or the GTX 780 (particularly if you’ve a custom overclocked model) you’re likely not be seeing a large improvement over what you’ve already got.
In fact, rumors persist we’ll be seeing a die shrunk version of the Maxwell’s at some point next year. Word around the water cooler is TSMC, who’re responsible for the production of both AMD and Nvidia’s GPU’s are having a little trouble with 20nm, hence the delay in production. So we’ll likely be seeing the Geforce GTX 980 with go faster stripes at some point next year.
Overclockers UK gibbo confirms 8GB GDDR5 Maxwell cards and GTX 980 slower than the Kepler based 780 Ti.

It does make buying right now quite difficult – if you’re in the market for a GTX 780 priced card then you might be best to wait, and depending on the price gouging at Maxwell’s launch you may or may not be better off. If you’re already the owner of a higher end GPU setup it’s going to be hard to justify an upgrade. I don’t think many GTX 780 SLI owners would want to upgrade, especially since rumors persist that these first Maxwell’s are just a taste of what’s to come. Then again, the additional VRAM might well be nice – particularly for those who’re gaming at say 4K.
And what of the GeForce GTX 980 Ti? No word yet – but it’s a pretty safe bet that it’s coming. Just how much faster it’ll be Keplar is of course at best a guess. It’s safe to assume that if rumors of the GTX 980′s performance are accurate, then the Ti version won’t exactly be a revelation.
Below are a list of rumored Maxwell specs versus the known specs of current Kepler cards. It’s important to remember to take these specs with a large truckload of salt – particularly the memory bandwidth of the 970 and the 980 GPU’s. Of course it could be a situation where Nvidia have done similar to AMD with the R9 285 (see our review) and improved the bandwidth efficiency so a wider bus isn’t required. The issue however is that it’s still suspicious as to the reasons by the 980 and 980 share the same bandwidth figures.

In other news, Maxwell is coming – Nvidia have announced Game24, a worldwide event aimed at… well, gamer’s. This event will take place on September 18th, and you can either attend it physically or watch the live streamed event. Interestingly enough, this happens to be the exact date that Maxwell is rumored to be announced. If you’d like more information feel free to check out their official website here.
This comes shortly after AMD have hosted their own live event, and will focus a lot on eSports, gaming stunts, developer demos and interviews, and of course a chance for Nvidia to build the hype train. These are the locations for the event, some haven’t yet been fully confirmed.

Pelos vistos vão-se focar só em descer consumos...

[Dape_1904]

É tipo Intel.

[Sonas]

Bem acho que fico pela 780 então

A LDLC estava com uma promoção de levar uma 780 pelo preço de uma 770, concretamente o modelo Zotac

[JayDz]

Isto so vão ser bom para o pessoal que quiset fazer upgrades para 780(ti)

A 770 que desça de preço também que eu agradeço lol

[Filipe]

n00b time, será que não haverá necessidade de aumentar performance das gráficas mas sim reduzir os consumos? Digo isto visto que as consolas limitam muito a qualidade gráfica dos jogos e as gráficas atuais lidam bem com eles? Talvez eles estejam a guardar o aumento de performance quando for necessário. Digo isto sem certezas nenhumas.

Para 1080p a 60Hz, as actuais topo de gama são mais do que suficientes, o problema é que já existe bastante gente a 1440p, o 4K está a tornar-se uma realidade com monitores cada vez mais baratos, já para não falar dos 120Hz/144Hz, que exigem uma gráfica bastante poderosa.

Por outro lado, isto acaba por ser bom para quem tem uma GTX 7xx ou R9 290/290X, que continua com uma gráfica actual e sem desvalorizar tanto. De qualquer modo, será de esperar para mais tarde a substituta da Ti, duvido que a Nvidia deixe a single rainha pertencer a uma geração passada.

The First GeForce GTX 980 Benchmarks ?

Following the 3DMark scores Videocardz then fabricated and guesstimated a performance chart where they shows some numbers (by extrapolating the 3DMark scores and estimating performance) based on the 3DMark scores. I'd be very hesitant to take these number seriously. Regardless it is an interesting post on a slow Sunday. It will not be much longer before we'll be testing these graphics cards ourselves. Only then you'll be objectively able to hear and read the real numbers. All the screen-shots below are all courtesy of Videocardz.

[Winjer]

Isso não são benchmarks da gráfica, mas sim estimativas que o VGchartz fez tendo em conta estimativas das unidades de execução que estas gráficas terão.

[Filipe]

Sim eu sei. Coloquei por que penso que não deve andar muito longe da realidade.


Edit: Ou então é como diz uns comentários na caixa, é mais um bait&click.

[LPC]

Boas!
Mais valia um refresh como a AMD fez com as 79xx para as 28x...
Isto não vale a pena criar uma nova arquitectura para ficarem exactamente onde estão...

Não acredito que vamos ter assim tantos ganhos no consumo para justificar o produto...

Cumprimentos,

LPC

O problema é que o mercado está estagnado há quase 3 anos.
Tanto a nVidia como a AMD começam a sentir a pressão dos consumidores e OEMs para lançarem alguma coisa.
Por isso é que temos produtos destes. Não são rebrands, mas também não são produtos realmente novos pois não trazem nada de realmente novo.
O desempenho fica igual, os preços pouco mudam, uma ou outra feature nova, talvez uns watts a menos e pouco mais....

Enquanto não vierem os 20nm, não vamos ver nada de realmente novo.

[Jorge-Vieira]

Mais do mesmo, nada de novo.
Enquanto nao avañ0nçarem para outro processo de fabrico vamos continuar na mesma.
