![]() ![]() Now you could choose a third computer that has 12 cores running at 1.8 GHz that costs the same as the 6-core, 3.6 GHz computer. You know the 3.6 GHz computer is more expensive than the 1.8 GHz computer. If you have a 1.8 GHz computer and a model runs in 2 hours, if you move it to a 3.6 GHz computer, it would run in 1 hour (they both have 6 cores). The clock speed determines how fast a given program will run. One has 6 cores running at 3.7 GHz while the other has 12 cores running at 1.9 GHz. Pretend those two processors cost the same and you have to choose which one to purchase. There are 29 products that are e5-2600-v4, out of the 44 products in the e5-v4 family. Below I plotted all 44 processor with the Clock frequency (GHz) versus the number of Cores. "The site suggests e5 2600 v4 cpu" Look at this reference. If you purchase a computer with a 1.8 GHz clock, your new computer will take twice as long to do most things than your current computer, which would be disappointing even if it had 14 cores and solved CFD models faster. ![]() Your current computer has a Core i7-4790 processor, which has 4 cores at 3.6 GHz. But my testing showed GPUs were not accelerating my Static Structural models. Get a supported GPU if you can afford it. Use a HDD for archive storage that is really large. I have an SSD for the C: drive so programs load fast, a much larger SSD where the projects I am working on are solved. They are much faster on large problems when you run out of RAM. Get SSD storage instead of HDD if you can afford it. Some vendors offer well engineered overclocked processors such as BOXX. However, don't trade off clock speed to get more cores. Get the fastest processor with 4 or more cores if you can afford it. This allows for a future RAM upgrade, say when you change from a Student license to a Research license. Find out the maximum RAM capability of the motherboard, even if you don't install the maximum initially. That will ensure a good user experience with the product. The most important thing is to get a graphics card from the list of tested cards. Which license are you on: Student (limited size) or a Research/Corporate (unlimited size) license? You don't need as much RAM if you can't run large models.ĭoes it need to be mobile or can you get a desktop? 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.What is your budget? There are different recommendations if you are a poor student versus having some else pay for an awesome workstation. 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. It measures how much data can be sent at one to and from the memory.Ī final point of comparison is the TDP (Thermal Design Power), a measurement of how much energy is lost as heat when a GPU is running. In constast, the memory bus width doesn't directly impact performance but rather the memory bandwidth. Higher speed is better as the graphics card won't need to wait for memory access before rendering a frame to the screen. In addition, memory bandwidth relates to the speed at which the GPU memory can be accessed. Too little memory may result in stuttering as the GPU tries to swap and fit everything in memory. A higher core clock speed may cause higher heat output, however.įurthermore, 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. When thermals and power delivery allow, the GPU will raise its core clock to the boost clock for even more performance. Compare GPU SpecsĬore Clock speed and Boost clock speed directly influence gaming performance of similar cards, typically the higher, the better. ![]() If benchmark scores aren't enough, you can also compare raw GPU performance and technical specs. Our comparison allows you to view the advantages and disadvantages of each spec for spec. If heat and noise is a concern, in a laptop computer for instance, you may want to find the most efficient GPU. When gaming on a high-resolution monitor, you may want to find the best value graphics card with the most memory. This is a test of gaming and compute performance. If you want the best GPU on the market, you can compare the hardwareDB GPU benchmark scores of each, the highest score wins. Compare two graphics cards using the form above, or select a pair from the popular comparisons section.įinding the best GPU for your needs can depend on many factors. What is the best graphics card? Our comparison tool will help you find out. ![]()
