In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R5 235X are noticeably better than the Nvidia GeForce 6800 Ultra.

The Radeon R5 235X was released over three years more recently than the GeForce 6800 Ultra, and so the Radeon R5 235X is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 6800 Ultra when running the latest games.

The Radeon R5 235X has 768 MB more video memory than the GeForce 6800 Ultra, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The GeForce 6800 Ultra has 20.8 GB/sec greater memory bandwidth than the Radeon R5 235X, which means that the memory performance of the GeForce 6800 Ultra is slightly better than the Radeon R5 235X.

The Radeon R5 235X has 160 Shader Processing Units and the GeForce 6800 Ultra has 22. However, the actual shader performance of the Radeon R5 235X is 70 and the actual shader performance of the GeForce 6800 Ultra is 9. The Radeon R5 235X having 61 better shader performance is not particularly notable, as altogether the GeForce 6800 Ultra performs better when taking into account other relevant data.

The Radeon R5 235X requires 37 Watts to run and the GeForce 6800 Ultra requires 124 Watts. We would recommend a PSU with at least 400 Watts for the Radeon R5 235X. The GeForce 6800 Ultra requires 87 Watts more than the Radeon R5 235X to run. The difference is significant enough that the GeForce 6800 Ultra may have an adverse affect on your yearly electricity bills in comparison to the Radeon R5 235X.

GPU Mini Review

Mini ReviewOverview
Radeon R5 235X is an OEM only, entry-level Graphics Card based on the second revision of the Terascale Architecture.

The Second variant of the Terascale 2 Architecture is still manufactured with a 40nm technology and despite allowing more Stream Cores, their design remains more or less the same compared to the first variant.

It equips a GPU codenamed Caicos XT which has 2 Compute Units activated and thus offers 160 Shader Processing Units, 8 TMUs and 4 ROPs. The Central Unit Operates at 875MHz.

The GPU accesses a 1GB frame buffer of DDR3, through a 64-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The memory clock operates at 533MHz.

DirectX 11.0 Support (11.0 Hardware Default) and support for HD3D, Eyefinity, App Acceleration, PowerPlay and other technologies.

Cooling Solution
The Cooling Solution consists of a Single-Fan.

Power Consumption
With a rated board TDP of 37W, it requires at least a 400W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Radeon R5 235X is essentially a very fast Radeon HD 6450 v3.
Gaming benchmarks put its performance between GeForce GT 520 & GeForce GT 530.

System Suggestions
We recommend a modest processor (Intel Celeron) and 4GB of RAM for a system with Radeon R5 235X.
The groundbreaking new NVIDIA GeForce 6800 graphics processing units (GPUs) and their revolutionary technologies power worlds where reality and fantasy meet; worlds in which new standards are set for visual realism and quality, performance, and video functionality. The GeForce 6800 GPUs deliver powerful, elegant graphics to drench your senses, immersing you in unparalleled worlds of visual effects for the ultimate PC experience.
