According to Nvidia the CUDA cores offer now a concurrent execution of floating point and integer operations for increased performance in compute-heavy workloads of modern games. If you're comparing two laptop GPUs, you may take this into account when choosing between the two since a cooler laptop generally runs faster for longer.The Turing generation did not only introduce raytracing for the RTX cards, but also optimized the architecture of the cores and caches. Adequate cooling is essential for good performance. If temperatures get too high (typically around 100☌ or 200☏), the GPU will lower its performance in order to prevent damage to the chip.

This has an impact on system temperatures. TDP (Thermal Design Power) is a measurement of how much energy is lost as heat when a GPU is running. It measures how much data can be sent at one to and from the memory. The memory bus width doesn't directly impact performance but it affects the memory bandwidth. Memory bandwidth relates to the speed at which the GPU memory can be accessed, higher speed is better as the graphics card won't need to wait for memory access before rendering a frame to the screen. Too little memory may result in stuttering as the GPU tries to swap and fit everything in memory. Memory is important for high resolutions and high resolution textures in games, if you're gaming at 4K or even 8K lots of memory is required. A higher core clock speed may cause a higher TDP however. When thermals and power delivery allow, the GPU will raise its core clock to the boost clock for even more performance. Graphics card specificationsĬore Clock speed and Boost clock speed directly affect gaming performance, typically the higher the better. Our overall benchmark score measures CPU performance in gaming and compute scenarios.

Use the table to the left to compare both GPUs, the advantages and disadvantages of each are shown. In terms of raw gaming performance in our GPU benchmark, the GeForce GTX 970 is better than the GeForce GTX 750 Ti. TDP (Thermal Design Power) measures total heat output from the chip. In addition, the GeForce GTX 750 Ti has a significantly lower TDP at 60 W when compared to the GeForce GTX 970 at 145 W. If you're planning at playing games at high resolutions with high quality textures, you will need a lot of memory. The allows for higher performance in certain scenarios.įurthermore, the spec sheet for both these GPUs show that they both have the same amount of memory at 4 GiB. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. In addition, the GeForce GTX 970 also has a slightly higher boost clock speed. This metric makes sense when comparing GPUs of a similar architecture or generation. The core clock speed (or base speed) is the frequency at which the GPU core runs. The GeForce GTX 970 has a slightly higher core clock speed.
