In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 3850 AGP are noticeably better than the Nvidia GeForce GT 340.

The HD 3850 has a 118 MHz higher core clock speed than the GeForce GT 340, but the GeForce GT 340 has 16 more Texture Mapping Units than the HD 3850. As a result, the GeForce GT 340 exhibits a 6.9 GTexel/s better Texture Fill Rate than the HD 3850. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 3850 has a 118 MHz higher core clock speed and 8 more Render Output Units than the GeForce GT 340. This results in the HD 3850 providing 6.3 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 GeForce GT 340 was released over a year more recently than the HD 3850, and so the GeForce GT 340 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 3850.

The GeForce GT 340 has 512 MB more video memory than the HD 3850, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GT 340 also has superior memory performance overall.

The GeForce GT 340 has 1.3 GB/sec greater memory bandwidth than the HD 3850, which means that the memory performance of the GeForce GT 340 is marginally better than the HD 3850.

The GeForce GT 340 has 96 Shader Processing Units and the Radeon HD 3850 AGP has 320. However, the actual shader performance of the GeForce GT 340 is 121 and the actual shader performance of the HD 3850 is 214. The HD 3850 having 93 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 3850 delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce GT 340.

The GeForce GT 340 transistor size technology is 15 nm (nanometers) smaller than the HD 3850. This means that the GeForce GT 340 is expected to run slightly cooler and achieve higher clock frequencies than the HD 3850.

The GeForce GT 340 requires 69 Watts to run and the Radeon HD 3850 AGP requires 75 Watts. We would recommend a PSU with at least 300 Watts for the GeForce GT 340 and a PSU with at least 450 Watts for the HD 3850. The HD 3850 requires 6 Watts more than the GeForce GT 340 to run. The difference is not significant enough for the HD 3850 to have a noticeably larger impact on your yearly electricity bills than the GeForce GT 340.

GPU Mini Review

Mini ReviewGeForce GT 340 is a middle-class GFX based on the 2009, 40nm, second-generation unified architecture.
It's based on the GT215 Core and offers 96 Shader Processing Units, 32 TMUs and 8 ROPs, on a 128-bit memory interface of fast GDDR5. The central unit runs at 550MHz and the memory clock operates at up to 850MHz.
The number of Shaders cannot be compared to GeForce GT 320 due to being based on a different architecture. It's therefore a renamed GeForce GT 240 GDDR5 (OEM).
Today's modern demanding games will have to be played at medium settings to achieve fluent frame rates. DirectX 11 games aren't supported.
Radeon HD 3850 AGP is a variant of the high-end Radeon HD 3850 based on the 55nm, second unified shader architecture, R600. Check its page to know more about its Core.
Compared to Radeon HD 3850, it features twice as much video memory and an AGP 8X Bus Interface. Benchmarks indicate the double sized frame buffer benefits this GPU largely and so its performance is up to 8% better than the reference Radeon HD 3850.
Today's modern games should run fluently at medium settings but with modest resolutions. DirectX 11 games aren't supported.
