I presume this is to do with things like DOF & motion blur etc, that there is a decreasing return when it comes to budget GPUS?ĮDIT: Wait a minute, I had the auto-tile addon active - guess I’ll try again.ĮDIT Again: Spoke too soon, if anything, it made matters worse for the GPU, 9 min 3 secs with a 128 size tile on the GPU as opposed to the larger size determined by AutoTile. We compared two Desktop platform GPUs: 1024MB VRAM GeForce GT 730 and 2GB VRAM GeForce GTX 750 Ti OEM to see which GPU has better performance in key. Just did the BMW scene, not the results I expected at all, the GPU is barely quicker than the CPU, yet in some things I render, it outperforms it by some margin. Don’t think the extra 5W power draw should impact my system overly, I only have 1 SATA 1TB drive, 8GB of ram, a DVD recorder and a couple of case fans to power, the current GPU draws a max of 28W so I suppose I’m only asking for an extra 30w. I had considered both, for the extra 20 quid or so, wasn’t sure the difference between the 750 and 750ti was relevant but I suppose if I’m going for the upgrade, every added Cuda core helps. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.Thanks for the info chaps, guess I’ll be getting one when my pension comes up next month. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. It is measured in millions of texels in one second. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). Comparison of the technical characteristics between the graphics cards, with Nvidia GeForce GTX 750 Ti on one side and Gigabyte GeForce GT 730 GV-N730-2GI. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. Since stream processors or CUDA cores are also used as vertex and geometry shaders for 3D image generation, higher performance is also beneficial to games. Higher single-precision performance number means the graphics card will perform better in general computing applications. ![]() Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. The NVIDIA GeForce GTX 750 Ti has an upper hand here. It features 768 SPUs, 48 TAUs, and 32 ROPs. It also makes use of a 128-bit memory bus, and uses a 14 nm design. It especially helps with AA, High Dynamic Range and higher screen resolutions. The GeForce GTX 1050 Ti features a core clock frequency of 1290 MHz and a GDDR5 memory speed of 1750 MHz. The higher the memory bandwidth, the better the card will be in general. If the card has DDR type memory, it must be multiplied by 2 once again. It's calculated by multiplying the card's bus width by its memory clock speed. Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second.
