Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 9800 GTX are massively 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 48 more Texture Mapping Units than the GeForce GT 720. As a result, the GeForce 9800 GTX exhibits a 30.4 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.
|Mini Review||Overview |
GeForce GT 720 is a Middle-Class Graphics Card based on the Second Revision of the Kepler Architecture.
This Graphics Card Equips the Kepler GK208 GPU which is essentially a power optimized version of the GK107 GPU. Whereas it still has a count of 2 Stream Multiprocessors, the bus-width has been cut in half to allow for even a smaller power consumption and consequently a cooler operating temperature.
Additionally, the GK208 GPU allows the Central Unit to reach a significant higher frequency, thanks to the Kepler Boost 2.0 Technology. The better the laptop's cooling system, the higher the frequency.
It equips a GPU Codenamed GK208 which has 1 Stream Multiprocessor activated and thus offers 192 Shader Processing Units, 16 TMUs and 16 ROPs. The Central Unit is clocked at 797MHz.
The GPU accesses a 1GB frame buffer of DDR3, through a 128-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 900MHz.
DirectX 12.0 Support (11.0 Hardware Default) and support for Optimus, CUDA, OpenCL, DirectCompute, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies
With a rated board TDP of 19W, it requires at least a 300W PSU and it relies entirely on the PCI Slot for power, meaning no extra connectors are required.
Gaming benchmarks put its performance on average with the older GeForce GT 530.
We recommend a Modest Processor (Pentium G) and 8GB of RAM for a system with GeForce GT 720.
GeForce 9800 GTX is a High-End Graphics Card based on the Tesla Architecture.
Tesla was NVIDIA's First Unified Shader Architecture.
It equips a GPU Codenamed G92-420-A2 which has 8 Stream Multiprocessors activated and thus offers 128 Shader Processing Units, 64 TMUs and 16 ROPs. The Central Unit is clocked at 675MHz.
The GPU is equipped with GDDR3 and Accesses the Frame Buffer through a 256-bit Memory Interface. The Memory Clock Operates at 1100MHz.
Memory: Frame Buffer
The GPU can fill up a Memory Pool of up to 512MB. Therefore, Gaming above 720p will be a problem.
With a rated board TDP of 140W, it requires at least a 450W PSU and it requires at least two 6-pin available connectors.
GeForce 9800 GTX offers around 10% better performance than GeForce 9800 GT.
