In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 3800 series are significantly better than the AMD Radeon R5 235X.

The HD 3800 has no core clock speed set, so any comparison between Texture and Pixel Fill Rates is not currently possible.

The Radeon R5 235X was released over three years more recently than the HD 3800, 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 HD 3800 when running the latest games.

The Radeon R5 235X has 512 MB more video memory than the HD 3800, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Radeon R5 235X also has superior memory performance overall.

The Radeon R5 235X has 14.4 GB/sec greater memory bandwidth than the HD 3800, which means that the memory performance of the Radeon R5 235X is slightly better than the HD 3800.

The Radeon R5 235X has 160 Shader Processing Units and the Radeon HD 3800 series has 320. However, the actual shader performance of the Radeon R5 235X is 70 and the actual shader performance of the HD 3800 is 0. The Radeon R5 235X having 70 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon R5 235X delivers a marginally smoother and more efficient experience when processing graphical data than the HD 3800.

The Radeon R5 235X transistor size technology is 15 nm (nanometers) smaller than the HD 3800. This means that the Radeon R5 235X is expected to run slightly cooler and achieve higher clock frequencies than the HD 3800.

The Radeon R5 235X requires 37 Watts to run but there is no entry for the Radeon HD 3800 series. We would recommend a PSU with at least 400 Watts for 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.
Radeon HD 3800 Series is not a GPU but instead a combination between Radeon HD 3830, Radeon HD 3850 and Radeon HD 3870 whose rank is a balance between the three and that exists for System Requirements purposes only.
