Latest benchmarks of NVIDIA's upcoming GeForce GTX 770 graphics card have been unveiled by Chiphell (via Videocardz). The GeForce GTX 770 that launches on 31st May would be the follow up card to the GeForce GTX 780 that launches on 23rd May 2013.

NVIDIA GeForce GTX 770 Gaming Performance Unveiled

The GeForce GTX 770 would make use of the GK104-425-A2 GPU that features 1536 Cuda cores, 128 TMUs and 32 ROPs along with a 2GB GDDR5 memory that operates along 256-bit interface. From previous reports, we know that the reference models would be clocked at 1059 MHz core and 1076 MHz boost while the memory would be effectively clocked at 7 GHz which would give a good performance boost over the GeForce GTX 680. Unlike the GeForce GTX 780 which would be restricted to reference models at launch, the GeForce GTX 770 would be made available in both reference and non-reference models. Some manufacture's would stick to the reference GeForce GTX 680 coolers to cut down the cost or use the NVTTM Titan cooler on the reference card. We know of atleast one model which comes from MSI that uses the custom Lightning series design while the one tested by the forum member here is another non-reference model.

The user mentions that the GeForce GTX 680 made use of HY ROC particles for memory which limited its overclocking limit upto 7.2 GHz max. The GeForce GTX 770 makes use of the HY R2C particles which can extend the overclocking limit so that at reference the GPU can be shipped at a clock speed of 7 GHz while allowing an on air OC of upto 8.00 GHz. The card tested makes use of a reference PCB but makes use of a tri-fan cooler that will improve its temperatures.

The card was tested in several gaming benchmarks along with 3DMark Firestrike testing, results can be seen below:

3DMark FireStrike (Extreme):

NVIDIA GeForce GTX 770: 3535 Marks

3535 Marks NVIDIA GeForce GTX 680: 3150 Marks

3DMark FireStike (Performance):

NVIDIA GeForce GTX 770: 7078 Marks

7078 Marks NVIDIA GeForce GTX 680: 6331 Marks

3DMark 11 (Extreme):

NVIDIA GeForce GTX 770: 3840 Marks

3840 Marks NVIDIA GeForce GTX 680: 3411 Marks

3DMark 11 (Performance):

FarCry 3 (1920x1080):

NVIDIA GeForce GTX 770: 70.9 FPS

70.9 FPS NVIDIA GeForce GTX 680: 79.8 FPS

CRYSIS 3 (1920x1080):

NVIDIA GeForce GTX 770: 42.9 FPS

42.9 FPS NVIDIA GeForce GTX 680: 39.1 FPS

TOMB RAIDER (1920x1080):

NVIDIA GeForce GTX 770: 87.3 FPS

87.3 FPS NVIDIA GeForce GTX 680: 78.3 FPS

Overall, we are looking at an average 10% increase over the GTX 680 from a reference GTX 770. Consider around +5/+10 % improvement in factory overclocked models based on their clock frequencies.
