Gaming Performance Comparison

In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 9800 GTX are significantly better than the Nvidia GeForce GT 720.

The GeForce GT 720 has a 122 MHz higher core clock speed than the GeForce 9800 GTX, but the GeForce 9800 GTX has 40 more Texture Mapping Units than the GeForce GT 720. As a result, the GeForce 9800 GTX exhibits a 25 GTexel/s better Texture Fill Rate than the GeForce GT 720. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GeForce GT 720 has a 122 MHz higher core clock speed than the GeForce 9800 GTX, but the GeForce 9800 GTX has 8 more Render Output Units than the GeForce GT 720. As a result, the GeForce 9800 GTX exhibits a 4.4 GPixel/s better Pixel Fill Rate than the GeForce GT 720. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GeForce GT 720 was released over three years more recently than the GeForce 9800 GTX, and so the GeForce GT 720 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 9800 GTX when running the latest games.

The GeForce GT 720 has 512 MB more video memory than the GeForce 9800 GTX, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GeForce 9800 GTX has superior memory performance.

The GeForce 9800 GTX has 56 GB/sec greater memory bandwidth than the GeForce GT 720, which means that the memory performance of the GeForce 9800 GTX is much better than the GeForce GT 720.

The GeForce GT 720 has 192 Shader Processing Units and the GeForce 9800 GTX has 128. However, the actual shader performance of the GeForce GT 720 is 153 and the actual shader performance of the GeForce 9800 GTX is 216. The GeForce 9800 GTX having 63 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce 9800 GTX delivers a significantly smoother and more efficient experience when processing graphical data than the GeForce GT 720.

The GeForce GT 720 transistor size technology is 37 nm (nanometers) smaller than the GeForce 9800 GTX. This means that the GeForce GT 720 is expected to run much cooler and achieve higher clock frequencies than the GeForce 9800 GTX.

The GeForce GT 720 requires 19 Watts to run and the GeForce 9800 GTX requires 140 Watts. We would recommend a PSU with at least 300 Watts for the GeForce GT 720 and a PSU with at least 450 Watts for the GeForce 9800 GTX. The GeForce 9800 GTX requires 121 Watts more than the GeForce GT 720 to run. The difference is significant enough that the GeForce 9800 GTX may have an adverse affect on your yearly electricity bills in comparison to the GeForce GT 720.

GPU Mini Review

Mini ReviewThis Graphics Card has 2 variants: one paired with DDR3 and another with GDDR5. This is the DDR3 version.

GeForce GT 720 is a middle-class level Graphics Card still based on the 28nm, Kepler architecture.

GeForce GT 720 offers the energy optimized GK208 Core with a SMX count of 1 and thus comes with 192 Shader Processing Units, 16 TMUs and only 8 ROPs, this on a 64-bit memory of 1GB of standard DDR3. While the central unit runs at 797MHz, the memory clock operates at 900MHz. The rated board TDP is of 19 Watts.

GeForce GT 720's performance is therefore reduced and only on pair with today's most powerful integrated graphics.
This Graphics Card needs to be paired with a decent modern processor and should only be used on a gaming mode below 720p, for optimal performance.
The NVIDIA GeForce 9800 GTX-based graphics card enables full-throttle lifelike game play while providing optimal power management with HybridPower technology. The PureVideo HD engine also delivers unmatched video and movie quality and SLI compatibility provides amplified performance when coupled with NVIDIA nForce SLI-ready motherboards. Dollar-for-dollar, this GPU packs great performance.
