In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 8600 GT 512MB GDDR3 are significantly better than the AMD Radeon HD 8450 (OEM).

The HD 8450 has a 85 MHz higher core clock speed than the 8600 GT, but the 8600 GT has 8 more Texture Mapping Units than the HD 8450. As a result, the 8600 GT exhibits a 3.6 GTexel/s better Texture Fill Rate than the HD 8450. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 8450 has a 85 MHz higher core clock speed than the 8600 GT, but the 8600 GT has 4 more Render Output Units than the HD 8450. As a result, the 8600 GT exhibits a 1.8 GPixel/s better Pixel Fill Rate than the HD 8450. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 8450 was released over three years more recently than the 8600 GT, and so the HD 8450 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 8600 GT when running the latest games.

The Radeon HD 8450 (OEM) and the GeForce 8600 GT 512MB GDDR3 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The 8600 GT has 13.9 GB/sec greater memory bandwidth than the HD 8450, which means that the memory performance of the 8600 GT is slightly better than the HD 8450.

The Radeon HD 8450 (OEM) has 160 Shader Processing Units and the GeForce 8600 GT 512MB GDDR3 has 32. However, the actual shader performance of the HD 8450 is 50 and the actual shader performance of the 8600 GT is 43. The HD 8450 having 7 better shader performance is not particularly notable, as altogether the 8600 GT performs better when taking into account other relevant data.

The HD 8450 transistor size technology is 40 nm (nanometers) smaller than the 8600 GT. This means that the HD 8450 is expected to run much cooler and achieve higher clock frequencies than the 8600 GT.

The Radeon HD 8450 (OEM) requires 18 Watts to run and the GeForce 8600 GT 512MB GDDR3 requires 46 Watts. We would recommend a PSU with at least 300 Watts for the HD 8450 and a PSU with at least 350 Watts for the 8600 GT. The 8600 GT requires 28 Watts more than the HD 8450 to run. The difference is not significant enough for the 8600 GT to have a noticeably larger impact on your yearly electricity bills than 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).
GeForce 8600 GT 512MB GDDR3 is one of the many variants of the fast-middle-class GeForce 8600 GT.
On this version, the GPU is equipped with 512MB of standard GDDR3. The architecture allows the use of 512MB, since the GPU's processing power is strong enough and the memory controller is up for the task of processing 512MB. Therefore, the performance is superior to the 256MB version and any other version of DDR2, including 1GB.
However, and due to its architecture limitations, modern demanding games will require reduced settings, even if they don't require more than 512MB of video ram. Very Demanding games like Metro 2033 are only playable at the lowest settings.
