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 6450A.

The HD 7750 has a 175 MHz higher core clock speed and 24 more Texture Mapping Units than the Radeon HD 6450A. 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 HD 6450A. 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 7750 was released over a year more recently than the Radeon HD 6450A, and so the HD 7750 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon HD 6450A.

The Radeon HD 7750 VTX3D 1GB DDR3 Edition and the Radeon HD 6450A 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 HD 6450A, which means that the memory performance of the HD 7750 is slightly better than the Radeon HD 6450A.

The Radeon HD 7750 VTX3D 1GB DDR3 Edition has 512 Shader Processing Units and the Radeon HD 6450A has 160. However, the actual shader performance of the HD 7750 is 348 and the actual shader performance of the Radeon HD 6450A is 50. 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 HD 6450A.

The HD 7750 transistor size technology is 12 nm (nanometers) smaller than the Radeon HD 6450A. This means that the HD 7750 is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 6450A.

The Radeon HD 6450A requires 25 Watts to run but there is no entry for the HD 7750. We would recommend a PSU with at least 400 Watts for the HD 7750 and a PSU with at least 300 Watts for the Radeon HD 6450A. The HD 7750 has been recommended a PSU with 100 Watts more than the Radeon HD 6450A. The difference is significant enough that the HD 7750 may have an adverse affect on your yearly electricity bills in comparison to the Radeon HD 6450A.

GPU Mini Review

Mini ReviewRadeon 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.
Overview
Radeon HD 6450A is a Mobile Entry-Level Graphics Card, used In All-In-One PCs that is 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.

Power Consumption
With a rated board TDP of 25W, 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 6450A is essentially a mobile version of Radeon HD 6450 v3 and offers exactly the same performance.

System Suggestions
We recommend a modest processor (Intel Celeron) and 2GB of RAM for a system with Radeon HD 6450A.
