In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTS 450 are noticeably better than the Nvidia GeForce 9800 GT.

The GeForce GTS 450 has a 183 MHz higher core clock speed than the GeForce 9800 GT, but the GeForce 9800 GT has 24 more Texture Mapping Units than the GeForce GTS 450. As a result, the GeForce 9800 GT exhibits a 8.5 GTexel/s better Texture Fill Rate than the GeForce GTS 450. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GeForce GTS 450 has a 183 MHz higher core clock speed than the GeForce 9800 GT and the same number of Render Output Units. This results in the GeForce GTS 450 providing 2.9 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 GeForce GTS 450 was released over a year more recently than the GeForce 9800 GT, and so the GeForce GTS 450 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 9800 GT.

The GeForce GTS 450 has 512 MB more video memory than the GeForce 9800 GT, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GTS 450 also has superior memory performance overall.

The GeForce GTS 450 has 0.1 GB/sec greater memory bandwidth than the GeForce 9800 GT, which means that the memory performance of the GeForce GTS 450 is marginally better than the GeForce 9800 GT.

The GeForce GTS 450 has 192 Shader Processing Units and the GeForce 9800 GT has 112. However, the actual shader performance of the GeForce GTS 450 is 301 and the actual shader performance of the GeForce 9800 GT is 168. The GeForce GTS 450 having 133 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTS 450 delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce 9800 GT.

The GeForce GTS 450 transistor size technology is 25 nm (nanometers) smaller than the GeForce 9800 GT. This means that the GeForce GTS 450 is expected to run slightly cooler and achieve higher clock frequencies than the GeForce 9800 GT.

The GeForce GTS 450 requires 106 Watts to run and the GeForce 9800 GT requires 105 Watts. We would recommend a PSU with at least 400 Watts for the GeForce GTS 450 and a PSU with at least 400 Watts for the GeForce 9800 GT. The GeForce GTS 450 requires 1 Watts more than the GeForce 9800 GT to run. The difference is not significant enough for the GeForce GTS 450 to have a noticeably larger impact on your yearly electricity bills than the GeForce 9800 GT.

GPU Mini Review

Mini ReviewOverview
GeForce GTS 450 is a fast-middle-class Graphics Card based on the first revision of the Fermi Architecture.

Architecture
The Fermi Architecture is manufactured with a 40nm technology and uses a technique known as Hot Clocking: The Shaders are clocked twice as fast as the Central Unit. While this leads to a reasonable performance boost, it causes enormous amounts of energy dissipation, leading, ultimately, to a significantly higher operating temperature.
Fermi is also the first GPU architecture with fully cached memory access which increases memory performance.

GPU
It equips a GPU Codenamed GF106-250-KA-A1 which has 4 Stream Multiprocessors activated and thus offers 192 Shader Processing Units, 32 TMUs and 16 ROPs. The Central Unit is clocked at 783MHz.

Memory
The GPU accesses a 1GB frame buffer of fast GDDR5, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 902MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for SLI, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies.

Cooling Solution
The Cooling Solution consists of a Single-Fan.

Power Consumption
With a rated board TDP of 106W, it requires at least a 400W PSU and an available 6-pin connector.

Performance
Gaming benchmarks put its performance considerably above Radeon HD 6670.

System Suggestions
We recommend a decent processor (Intel Core i3) and 4GB of RAM for a system with GeForce GTS 450.
Overview
GeForce 9800 GT is a High-End Graphics Card based on the first revision of the Tesla Architecture.

Architecture
Tesla was NVIDIA's First Unified Shader Architecture.

GPU
It equips a GPU Codenamed G92-270-A2 which has 7 Stream Multiprocessors activated and thus offers 112 Shader Processing Units, 56 TMUs and 16 ROPs. The Central Unit is clocked at 600MHz.

Memory
The GPU accesses a 512MB frame buffer of GDDR3, through a 256-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 900MHz.

Features
DirectX 10.0 Support (10.0 Hardware Default) and support for SLI, NVIDIA PureVideo HD Technology, Dual-stream Hardware Acceleration, PhysX, CUDA, HybridPower and other technologies.

Cooling Solution
The Cooling Solution consists of a Single-Fan.

Power Consumption
With a rated board TDP of 105W, it requires at least a 400W PSU and it requires at least one 6-pin available connectors.

Performance
GeForce 9800 GT is a direct re-brand of GeForce 8800 GT.
Gaming benchmarks put its performance somewhat below a Radeon HD 4770, meaning it is much faster than Radeon HD 3870.
