In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8740 (OEM) are massively better than the AMD Radeon HD 6450A.

The HD 8740 has a 175 MHz higher core clock speed and 24 more Texture Mapping Units than the Radeon HD 6450A. This results in the HD 8740 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 8740 has a 175 MHz higher core clock speed and 12 more Render Output Units than the Radeon HD 6450A. This results in the HD 8740 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 8740 was released over a year more recently than the Radeon HD 6450A, and so the HD 8740 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 HD 8740 has 1024 MB more video memory than the Radeon HD 6450A, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 8740 also has superior memory performance overall.

The HD 8740 has 63.5 GB/sec greater memory bandwidth than the Radeon HD 6450A, which means that the memory performance of the HD 8740 is much better than the Radeon HD 6450A.

The Radeon HD 8740 (OEM) has 512 Shader Processing Units and the Radeon HD 6450A has 160. However, the actual shader performance of the HD 8740 is 348 and the actual shader performance of the Radeon HD 6450A is 50. The HD 8740 having 298 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 8740 delivers a massively smoother and more efficient experience when processing graphical data than the Radeon HD 6450A.

The HD 8740 transistor size technology is 12 nm (nanometers) smaller than the Radeon HD 6450A. This means that the HD 8740 is expected to run slightly cooler and achieve higher clock frequencies than the Radeon HD 6450A.

The Radeon HD 8740 (OEM) requires 55 Watts to run and the Radeon HD 6450A requires 25 Watts. We would recommend a PSU with at least 400 Watts for the HD 8740 and a PSU with at least 300 Watts for the Radeon HD 6450A. The HD 8740 requires 30 Watts more than the Radeon HD 6450A to run. The difference is not significant enough for the HD 8740 to have a noticeably larger impact on your yearly electricity bills than the Radeon HD 6450A.

GPU Mini Review

Mini ReviewOverview
Radeon HD 8740 (OEM) is an OEM Only, Fast-Middle-Class Graphics Card based on the First Revision of the Graphics Core Next (GCN) Architecture.

Architecture
The GCN Architecture succeeds the 40nm Terascale Architecture. In addition to being produced with a 28nm Technology, the GCN Architecture adds other Technologies that allow for energy efficiency. For example, ZeroCore Power, a long idle power saving technology, allows the Graphics Cards to shut down by itself when the Monitor is turned off.
GCN also adds Improved Anisotropic Filtering, DirectX 11 Tessellation and the Partially Resident Textures (PRT) Technology, which enables future games to utilize ultra-high resolution textures with the same performance as today's small and often repetitive textures.

GPU
It equips a GPU Codenamed Cape Verde PRO which has 8 Compute Units activated and thus offers 512 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is clocked at 800MHz.

Memory
The GPU accesses a 1GB frame buffer of fast GDDR5, through a 256-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1125MHz.

Power Consumption
With a rated board TDP of 55W, it requires at least a 400W PSU and relies entirely on the PCI Slot for power, meaning no extra connectors are required.

Performance
Radeon HD 8740 (OEM) is a Direct Rebrand of Radeon HD 7750 and performs exactly like it.

System Suggestions
Radeon HD 8740 (OEM) is best suited for resolutions up to and including 1600x900. We recommend a Decent Processor (Intel Core i3 Quad Core/AMD FX Quad Core) and 8GB of RAM for Optimal Performance.
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.
