graphics card, you only need to install the latest driver package with opencl. The following video cards support Double Precision Floating Point: NVIDIA geforce 200 series, 400 series, 500 series graphics cards; amd radeon HD 5800, 5900, 6900 series. The radeon 6900 series does not yet support the official dual-precision floating point number (cl_khr_fp64) extension, so this program also supports cl_amd_fp64 dual-precision floating point extension, which has the same functionality.

The CPU needs 0 cycles to access its registers, 1-30 cycles to access the cache, and 50-cycles to access the primary memory. For Intel Core i7. This value can be very specific. The Intel Core i7 clock speed is about 2-3 GHz. Can be calculated. L1-Instruction Cache L1-data

original images. Image Quality Comparison The same is true! It seems that the principle is different, but the visual anti-sawtooth effect is almost the same, a lot smoother than after the closure. Now, since the image quality is almost the same, the number of frames to fight is reduced by less.

. Many compilers do not support multi-threaded compilation, so the CPU frequency of a single core is more important. So it seems that the core CPU with turbo boost is very necessary, such as I3 or I5 are good. Of course there are conditions where i7 is better, but most people do not need such high performance. If you do not run a virtual machine or access the Internet, the CPU usage of the four cores will basically not exceed 50%, usually 0 ~ 25% is a

graphics card has a higher frequency (such as 3630qm and 3635qm, the maximum frequency of the latter core display is 1.2 GHz, and the former is 1.15 GHz ). HQ: a new generation of the fourth generation CPU. Its main parameters are the same as those of the standard quad-core CPU. However, it integrates the iris pro5200 series with unprecedented performance, the performance of this core display can be directly comparable to that of the mid-range independent graphics card.

pages requires hardware and OS kernel collaboration to complete. 4. Combining cache and virtual memoryMost systems access the cache in a way that chooses physical addressing. With physical addressing, it is easy for multiple processes to have storage blocks in the cache and share blocks from the same virtual page. Also, the cache does not need to deal with protection issues because access checks are part of the address translation process.5. Using TLB to accelerate address translationA small ca

after the pipeline deepens, a noticeable change can be brought about-the increase in clock frequency. Although we now know that high frequency does not mean good performance, but in fact, many ordinary consumers do not know this, and in those years, Intel and AMD and other manufacturers, in advertising is the processor frequency as the main performance indicators. This caused the consumer to buy a computer when they only asked, "What is your computer frequency?" ", it turned out to be a 2G, in

The processor of the graphics card is called the Graphics Processing device (GPU), which is the "heart" of the graphics card, similar to the CPU, except that the GPU is designed to perform complex mathematical and geometric calculations.GPU computing power is very powerful, for example: the current mainstream
