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 HD 8450 (OEM).

The HD 7750 has a 175 MHz higher core clock speed and 24 more Texture Mapping Units than the HD 8450. 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 HD 8450. 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 HD 8450 was released less than a year after the HD 7750, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The HD 7750 has 512 MB more video memory than the HD 8450, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7750 also has superior memory performance overall.

The HD 7750 has 17.1 GB/sec greater memory bandwidth than the HD 8450, which means that the memory performance of the HD 7750 is slightly better than the HD 8450.

The Radeon HD 8450 (OEM) has 160 Shader Processing Units and the Radeon HD 7750 VTX3D 1GB DDR3 Edition has 512. However, the actual shader performance of the HD 8450 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 HD 8450.

The HD 7750 transistor size technology is 12 nm (nanometers) smaller than the HD 8450. This means that the HD 7750 is expected to run slightly cooler and achieve higher clock frequencies than the HD 8450.

The Radeon HD 8450 (OEM) requires 18 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 HD 8450 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 HD 8450. The difference is significant enough that the HD 7750 may have an adverse affect on your yearly electricity bills in comparison to the HD 8450.

GPU Mini Review

Mini ReviewOverview
Radeon HD 8450 (OEM) is an OEM only, entry-level Graphics Card based on the second revision of the Terascale Architecture.

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.

GPU
It equips a GPU codenamed Caicos PRO which has 2 Compute Units activated and thus offers 160 Shader Processing Units, 8 TMUs and 4 ROPs. The Central Unit Operates at 625MHz.

Memory
The GPU accesses a 512MB frame buffer of GDDR3, through a 64-bit memory interface. The memory clock operates at 533MHz. The size of the frame buffer is adequate.

Features
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 18W, it requires at least a 300W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Performance
Radeon HD 8450 (OEM) is a Direct Rebrand of Radeon HD 6450 v2 and performs exactly like it.
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 HD 8450 (OEM).
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.
