In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8740 (OEM) are massively better than the AMD Radeon HD 5450 Gigabyte OC 512MB Edition.

The HD 8740 has a 100 MHz higher core clock speed and 24 more Texture Mapping Units than the HD 5450. This results in the HD 8740 providing 20 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 100 MHz higher core clock speed and 12 more Render Output Units than the HD 5450. This results in the HD 8740 providing 10 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 HD 5450, 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 HD 5450.

The HD 8740 has 1536 MB more video memory than the HD 5450, 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 59.2 GB/sec greater memory bandwidth than the HD 5450, which means that the memory performance of the HD 8740 is much better than the HD 5450.

The Radeon HD 5450 Gigabyte OC 512MB Edition has 80 Shader Processing Units and the Radeon HD 8740 (OEM) has 512. However, the actual shader performance of the HD 5450 is 56 and the actual shader performance of the HD 8740 is 348. The HD 8740 having 292 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 HD 5450.

The HD 8740 transistor size technology is 12 nm (nanometers) smaller than the HD 5450. This means that the HD 8740 is expected to run slightly cooler and achieve higher clock frequencies than the HD 5450.

The Radeon HD 8740 (OEM) requires 55 Watts to run but there is no entry for the HD 5450. We would recommend a PSU with at least 400 Watts for the HD 5450 and a PSU with at least 400 Watts for the HD 8740. The two GPUs have been recommended a PSU with the same amount of wattage. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewRadeon HD 5450 Gigabyte OC 512MB Edition is a special edition of the entry-level Radeon HD 5450.
This edition comes overclocked out of the box in the core-clock which went from 650MHz to 700MHz.
Expect an up to 5% performance boost in most games, when compared to the reference card.
Overview
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.
