*Updated as of 2nd June 2013 - Originally published as a preliminary review on 30th May, we've since refreshed our comparison results to update the article to a full review, complete with ratings.
We begin our report of the GeForce GTX 770’s performance was 3DMark 11, a synthetic benchmark that evaluates a card’s DirectX 11 performance. It tests aspects such as tessellation and DirectCompute.
As we had expected, the GeForce GTX 770 is a faster card than the GeForce GTX 680 as evidenced by its higher 3DMark 11 scores. Its scores were about 6- to 7% higher for both settings and was just as much ahead of its rival, the AMD Radeon HD 7970 GHz edition. However, despite the higher clock speeds of its GK104 core, it was still no match for the GeForce GTX 780 and its pared down GK110 core.
3DMark (2013)'s Fire Strike benchmark is Futuremark's most ambitious and technical benchmark to date utilizing a grueling two-part test with extreme levels of tessellation and volumetric illumination, as well as complex smoke simulation using compute shaders and dynamic particle illumination, while Fire Strike Extreme ramps up the difficulty with more tessellation, more particle effects and more taxing DirectCompute calculations.
On 3DMark 2013 Fire Strike, the GeForce GTX 770’s lead over the GeForce GTX 680 was 7%; however, it was beaten by the Radeon HD 7970 GHz Edition with a slim margin of slightly over 2%. The two GK110-based cards - GeForce GTX Titan and GeForce GTX 780 - were untouchable. For the Fire Strike Extreme test, the GeForce GTX 770's lead was also about 7%, and the winning margin of the lone AMD Radeon card was narrowed to just 1%.
