Today Nvidia has introduced their second high-end GPU from the new Geforce 700 series – the GTX 770, just a week after the announcement of the new single-chip top model, namely the GeForce GTX 780. The new Geforce GTX 770 graphic cards will come by default with the same cooling as the GTX 780 and the GTX TITAN, or at least the reference design boards, however the partners will also be offering non-reference PCB designs and cooling solutions as well. The new GTX 770 is based on the GK104, unlike the GTX 780 and GTX TITAN that uses the GK110, actually the GTX 770 is more like an updated version of the GTX 680 than an update over the GTX 670. GeForce GTX 770 has the same number of CUDA Cores as the GTX 680, but the GPU is running at a bit higher clock, the memory configuration by default is 2GB GDDR5, with another 4GB version also available. The memory bus is still 256-bit as with the GTX 680, however the operating frequency of the new GTX is increased from 6 GHz to 7 GHz. Also the new GTX 770 features support for the GPU Boost 2.0 technology and is optimized for high performance silent operation thanks to the good cooler that also allows for a quite decent overclockbility of the card.


Specifications of GeForce GTX 770:

Graphics Card – GeForce GTX 770 2GB
CUDA Cores – 1536 +192
Texture Units (TMU) – 128 +16
Raster Operator Units (ROP) – 32
Graphics Clock (Base) – 1046 MHz +131
Graphics Clock (Boost) – 1085 MHz +136
Texture Fill Rate (Bilinear) – 133.9 GigaTexels/sec +31.4
Standard Memory Configuration – 2048 MB GDDR5
Memory Interface Width – 256-bit
Memory Clock – 3505 MHz (7010 effective) +501 (1002)
Memory Bandwidth – 224.3 GB/sec +32.1
Fabrication Process – 28 nm
Transistor Count – 3.54 Billion
Connectors – Dual-Link DVI-I, Dual-Link DVI-D, HDMI 1.4 High Speed, DisplayPort 1.2
Form Factor – Dual Slot
Power Connectors – 1x 6-pin, 1x 8-pin PEG
Power Consumption – 230W TDP +60
GPU Thermal Threshold – 95 degrees Celsius -2
Bus Interface – PCI Express 3.0

* The numbers in red and green represent the upgrade or downgrade of the specific parameter in the GTX 770 as compared to the GTX 670!

The best thing about the new GeForce GTX 770 is that the price of the cards based on it are going to cost the same as the GTX 670, while at the same time the performance they will be offering is expected to be slightly higher than what the more expensive GTX 680 does provide. So with the GTX 770 you are going to get more than the performance of a GTX 680, but with a lower price, so unless you already have GTX 680 in your PC you may consider upgrading to GTX 770 if the price of the GTX 780 or the GTX TITAN is a bit too much for you. Going for two GTX 770-based video cards in SLI configuration would be a great choice for getting higher performance at a more affordable price if you play games on a multi-monitor 2D or stereo 3D.

The New Nvidia GeForce GTX 780 GPUs Just Got Official

Today Nvidia has officially announced their new flagship GPU, the first form the 700 series – GeForce GTX 780 based on the GK110 Kepler architecture and manufactured using 28nm process. You can say that the new Nvidia GeForce GTX 780 is a more affordable lite version of the GTX TITAN announced not long ago, based on the same GK110 GPU, but with a little less video memory and a bit less CUDA cores. Other than that the things are looking very similar to what the GTX TITAN offers. You should have in mind though that the new GTX 680 is not here to replace the GTX TITAN, but to succeed the older GTX 680 (GK104) and looking at the specs it does that quite nicely…


Nvidia GeForce GTX 780 Specifications:

Graphics Card: GeForce GTX 780 3GB
Graphics Processing Clusters: 4 or 5
Streaming Multiprocessors: 12 -4
CUDA Cores: 2304 +768
Texture Units: 192 +64

GPU Boost Clock: 1058 MHz -158
Memory Clock (Data rate): 6008 MHz
L2 Cache Size: 1534KB +1024
Total Video Memory: 3072MB GDDR5 +1024
Memory Interface: 384-bit +128
Total Memory Bandwidth: 288.4 GB/s +96.14
Texture Filtering Rate (Bilinear): 165.7 GigaTexels/sec +36.9
Fabrication Process: 28 nm
Transistor Count: 7.1 Billion +3.56
Connectors: Dual-Link DVI-I, Dual-Link DVI-D, HDMI 1.4 High Speed, DisplayPort 1.2

* The superscript numbers in green and red show the change as compared to the specs of GTX 680.

What is new here is the GPU Boost 2.0 support that was introduced with the GTX TITAN and even though the new GTX 780 brings higher power consumption and more performance it still manages to operate silently under load. It seems however the silent operation is a somewhat compromise with he Boost performance as the GPU operated with higher temperatures under load and thus can hardly use the maximum GPU Boost. However playing a bit with the fan settings and the GPU Boost 2.0’s 80 degrees default temperature limit for the Boost frequency can help get the full potential from the GTX 780 even if you don’t plan to overclock it.

I’ve been playing with a GeForce GTX 780 card in the last few days, so you can expect some benchmarks about the performance of the card in stereoscopic 3D mode using 3D Vision in the next few days. For now I can tell you that I really like what I’m getting in terms of performance from the GTX 780 and I’m definitely planning to replace my two thrust worthy GTX 580 GPUs running in SLI with it. I’ve decided to skip the GTX 680 in terms of upgrade and while the GTX TITAN was a bit more expensive that it was worth, now the price of the GTX 780 and the performance it offers make it a great product for playing games in high-resolution 2D or in Full HD stereoscopic 3D mode. For multi-monitor setups, both in 2D and in stereo 3D, going for two cards would still probably be a better option in order not to have to eventually make some compromises.

Hopefully the first Full Cover water cooling blocks for the GeForce GTX 780 will not take a lot of time before appearing on the market, because if you combine the new GPU with a good water cooling solution it will turn out to be a perfect combination – silent and cool operation and very high performance as both the GTX 780 GPU and the video memory is very overclocker-friendly, all you need to do is have it cooled properly. But even with the stock air cooling you can get good overclock performance if you don’t mind having the cooling of the card running a bit noisier as the stock cooler has a lot of potential for overclocking if you don’t mind the noise. The new GeForce GTX 780 hits the right spot for a really high-performance GPU that is still quite affordable, ideal solution for the more demanding stereoscopic 3D gamers that already have powerful 3D Vision-ready computers setup for S3D gaming.
