In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7750 VTX3D 1GB DDR3 Edition are massively better than the AMD Radeon R5 230.

The HD 7750 has a 175 MHz higher core clock speed and 24 more Texture Mapping Units than the Radeon R5 230. This results in the HD 7750 providing 20.6 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 HD 7750 has a 175 MHz higher core clock speed and 12 more Render Output Units than the Radeon R5 230. This results in the HD 7750 providing 10.3 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 Radeon R5 230 was released over a year more recently than the HD 7750, and so the Radeon R5 230 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 7750.

The Radeon R5 230 and the Radeon HD 7750 VTX3D 1GB DDR3 Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 7750 has 17.1 GB/sec greater memory bandwidth than the Radeon R5 230, which means that the memory performance of the HD 7750 is slightly better than the Radeon R5 230.

The Radeon R5 230 has 160 Shader Processing Units and the Radeon HD 7750 VTX3D 1GB DDR3 Edition has 512. However, the actual shader performance of the Radeon R5 230 is 50 and the actual shader performance of the HD 7750 is 348. The HD 7750 having 298 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7750 delivers a significantly smoother and more efficient experience when processing graphical data than the Radeon R5 230.

The HD 7750 transistor size technology is 12 nm (nanometers) smaller than the Radeon R5 230. This means that the HD 7750 is expected to run slightly cooler and achieve higher clock frequencies than the Radeon R5 230.

The Radeon R5 230 requires 19 Watts to run but there is no entry for the Radeon HD 7750 VTX3D 1GB DDR3 Edition. We would recommend a PSU with at least 300 Watts for the Radeon R5 230 and a PSU with at least 400 Watts for the HD 7750. The HD 7750 has been recommended a PSU with 100 Watts more than the Radeon R5 230. The difference is significant enough that the HD 7750 may have an adverse affect on your yearly electricity bills in comparison to the Radeon R5 230.

GPU Mini Review

Mini ReviewOverview
Radeon R5 230 is an 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 625MHz.

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 19W, it requires at least a 300W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Radeon R5 230 is a direct re-brand of Radeon HD 6450 v3.
Gaming benchmarks put its performance around of a GeForce GT 420.

System Suggestions
We recommend a modest processor (Intel Celeron) and 2GB of RAM for a system with Radeon R5 230.
Radeon HD 7750 VTX3D 1GB DDR3 Edition is a special edition of the fast-middle-class Radeon HD 7750 1GB DDR3.
This version has no new features (when compared to the DDR3 version) and so it performs exactly like it.
