In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 660 Zotac AMP Edition are massively better than the AMD Radeon R7 240 Asus 1GB Edition.

The GTX 660 has a 316 MHz higher core clock speed and 60 more Texture Mapping Units than the R7 240. This results in the GTX 660 providing 69.1 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 660 has a 316 MHz higher core clock speed and 16 more Render Output Units than the R7 240. This results in the GTX 660 providing 19.3 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R7 240 was released over a year more recently than the GTX 660, and so the R7 240 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 660.

The GTX 660 has 1024 MB more video memory than the R7 240, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 660 also has superior memory performance overall.

The GTX 660 has 133 GB/sec greater memory bandwidth than the R7 240, which means that the memory performance of the GTX 660 is massively better than the R7 240.

The Radeon R7 240 Asus 1GB Edition has 320 Shader Processing Units and the GeForce GTX 660 Zotac AMP Edition has 960. However, the actual shader performance of the R7 240 is 212 and the actual shader performance of the GTX 660 is 1067. The GTX 660 having 855 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 660 delivers a massively smoother and more efficient experience when processing graphical data than the R7 240.

The Radeon R7 240 Asus 1GB Edition requires 30 Watts to run but there is no entry for the GeForce GTX 660 Zotac AMP Edition. We would recommend a PSU with at least 400 Watts for the R7 240.

GPU Mini Review

Mini ReviewOverview
Radeon R7 240 Asus 1GB Edition is a special edition of AMD's Middle-Class Radeon R7 240 2GB, created by Asus.

Overclock: Central Unit
The Central Unit runs at the same speed.

Overclock: Memory Clock
The Operating Memory Clock now operates at 800MHz and the Frame Buffer was halved to 1GB.

Cooling Solution
The Cooling System now features a Dust-proof Fan design which increases particle resistance and extends card lifespan by up to 25% longer than reference.

Without Overclocking Out of The Box, Radeon R7 240 Asus 1GB Edition is as fast as the reference Radeon R7 240 2GB.
GeForce GTX 660 Zotac AMP Edition a special edition of GeForce GTX 660.
The new features include a new cooling system and in terms of overclocking, the base-clock was increased from 980MHz to 1046MHz and the boost clock can now reach 1111MHz, instead of 1033MHz. The memory clock was raised to 1652MHz.
Benchmarks indicate a 5.5% performance when compared to the reference card.
