Report: GTX 770 Spotted Again, Specifications Confirmed
The graphics card will apparently pack the GK104 GPU with eight of the SMX units enabled. This would give the card a total of 1536 enabled CUDA cores, 128 TMUs, and 32 ROPs. The base clock would be 950 MHz, with the boost clock set at 980 MHz. The card would also have only 2 GB of GDDR5 memory, which would run at an effective speed of 6.00 GHz over a 256-bit memory bus, letting it pump out 192 GB/s of bandwidth. This makes the GPU and memory parts of the card almost identical to the GTX 680.
What appears to be different is the PCB design. Apparently, the card has a lot more overclocking headroom due to a standard TDP of 250 W (vs. the 195 W of the GTX 680). The default voltage would also be above 1.3 V. The card would be fueled by a 6-pin and 8-pin PCIe power connector setup. The PCB is reportedly much more similar to the design of the GTX Titan rather than the GTX 680, although this particular sample could be an engineering sample.
It also appears that the card will launch on May 30, 2013.
| GPU | CUDA Cores | TMUs | ROPs | Memory | Memory Interface | |
|---|---|---|---|---|---|---|
| GTX 780 | GK110 | 2,496 | 208 | 40 | 3 GB | 320-bit |
| GTX 770 | GK104-425 | 1,536 | 128 | 32 | 2 GB | 256-bit |
| GTX 760 Ti | GK104-225 | 1,344 | 112 | 32 | 2 GB | 256-bit |
either way, it's sounding more and more like this is a publicity stunt for Nvidia and their attempt to get even more money out of kepler, rather than being forced to drop prices as the current series age...
With next gen games coming out this year, and consoles putting much more emphases on memory capability compared to previous generation upgrades, I would imagine games coming out over the next 2 years to absolutely balloon on GPU ram requirements. And this will be doubbly true for PC gaming where better textures are typically the bonus to buying into the ecosystem. My next upgrade may not need that much GPU power, but I am thinking a minimum of at least 3-4GB of ram so that I do not get burnt again on capacity issues.
I might still get an AMD card for my next upgrade.
I really can't afford to upgrade, but I'd like to get another pricewar going on new hardware so I can make an excuse to.
Yup. The only 'new' thing they'll bring out is the 780 which is a slightly less powerful Titan then just move everything down a tier. Very disappointing. If the rumours are true about Volcanic Islands, hopefully that forces Nvidia's hand. Would love to see some hard fought competition about a year from now with Maxwell and VI.
Quick to say old? You still have a GTX590???
LOL just kidding, i know what you mean.
I am much more interested in the AWESOME software capabilities the Titan has. Damn that would be great on a lower end card too.
Monitor OCing?
All of that thermal/acoustic customization.
So much OCing potential compared to other Kepler cards.
Never heard of the 780 eh? I wouldn't buy that anyway, I want 20nm, but still, they have one just not the 770/760 which are still both going to be bumps in clocks. They will essentially be 10-15% faster for the same price as the ones they replace. AMD didn't do that with the ghz editions, they cost more on debut (still do last I checked).
