Due to the great changes of Intel’s 11th generation desktop processor, some of my friends have encountered a lot of confusion in the process of purchase or use. Based on this, on how to make good use of the core processor of the 11th generation desktop computer, I will share my experience with you this time.
Question 1: with 8 cores and 16 threads, is i9 better or i7 better?
The main difference between i9 and i7 is the frequency setting. The flagship core i9-11900k can reach 5.3GHz, while the core i7-11700k can reach 5.0ghz. By default, the difference between them is actually the 0.3ghz Rui frequency. You know, the starting price of the core i9-11900k is 4699 yuan, and the starting price of the core i7-11700k is 3299 yuan. To be fair, core i7-11700k is definitely more value-added, suitable for most players to choose!
In the author’s opinion, the core i7-11700 with only 65W TDP is also worthy of players’ attention. Its core frequency can reach 4.8ghz, and its performance is also very good.
Question 2: how about the game performance of core i5?
Core i5 has always been the first choice for mainstream game players to pursue high cost performance. How about the game performance of this generation of core i5?
Taking the core i5-11600k as an example, according to the author’s previous measurement, in many games, the core i5-11600k with the initial price of 2399 yuan has the performance of close to 4699 yuan, and the strength can not be underestimated. Therefore, players can rest assured to buy this generation of core i5.
Question 3: is z590 better or z490 better?
Z590 chipset motherboard can support pcie4.0 technology. Of course, some brands of z490 chipset motherboards also reserve pcie4.0 channel, and can open pcie4.0 channel by updating BIOS.
As far as I know, all z490 chipset motherboards of MSI can open pcie4.0 channel by updating BIOS. Therefore, players with MSI z490 motherboard in their hands do not need to replace the motherboard. They only need to upgrade an Intel 11th generation desktop processor to enjoy the powerful performance brought by pcie4.0 technology.
Question 4: can pcie4.0 be used only with the 11th generation processor and z590 motherboard?
yes! Since the pci4.0 controller is integrated into the 11th generation of smart Intel Core s series desktop processor of rocket lake, if you want to enjoy the excellent performance of pci4.0 devices, the z590 motherboard must be used with the 11th generation of smart intel core desktop processor of rocket lake.
Question 5: what is re size bar support?
When amd released the RX 6000 Series graphics card last year, it brought Sam video memory smart technology, which allows AMD processor to directly calculate the data in the video memory of AMD graphics card, thus improving the graphics performance of the computer.
Now, starting from the 11th generation of desktop processors, Intel and NVIDIA have also developed a technology similar to AMD Sam, called re size bar support, which allows Intel processors to directly calculate the data in the memory of NVIDIA graphics card, so as to improve the graphics performance of the computer.
Taking ASUS Rog maximum XIII hero motherboard as an example, the BIOS of the motherboard provides the re size bar support option, which is off by default and needs to be turned on manually.
If your current computer is the combination of Intel 11th generation desktop processor and NVIDIA geforce RTX 30 series graphics card, you can try re size bar support technology to further improve the game performance.
Question 6: how to adjust the memory frequency division mode of this generation of processors?
Intel’s 11th generation desktop processor and its platform add memory frequency division mechanism, including two memory frequency division modes, gear1 (1:1) and gear2 (1:2). This has become a hot topic in the major DIY hardware forum.
In this paper, core i7-11700 processor, Huaqing b560m-hdv-a motherboard, 2 × Take 8GB ddr4-3200 memory as an example. In the BIOS of Huaqing b560m-hdv-a motherboard, there is the option of DRAM gear mode, which is used to set the two memory frequency division modes of gear1 (1:1) or gear2 (1:2).
We can learn from the CPU-Z software that in the gear2 (1:2) memory frequency division mode, the frequency of the processor memory controller is only about 800MHz, half of the 1600MHZ memory frequency. After manually adjusting to gear1 (1:1) memory frequency division mode, the memory controller will keep the same frequency as the memory, which is 1600MHZ.
Faced with such a choice, is it better to choose gear1 (1:1) or gear2 (1:2)? The author has tried before, and then I will share my experience after the actual measurement.
Only according to the results of aida64 memory test program, gear1 (1:1) memory frequency division mode is better. The memory latency of gear2 (1:2) is 10 ns slower than that of gear1 (1:1), which is a big gap.
Although the memory latency performance will decline significantly after turning on gear2 (1:2), in many test projects, the results are very surprising.
For example, according to the test results of pcmark10, the performance of gear2 (1:2) is better.
Based on this, is it better to choose gear1 (1:1) or gear2 (1:2)? The author’s point of view is the specific application of specific settings!
If the running application relies heavily on the throughput of memory data, it is better to choose gear2 (1:2)! If you run an application that relies heavily on memory latency, it’s better to choose gear1 (1:1)!
Why does Intel have such a memory frequency division mechanism? I guess it may be preparing for the 12th generation desktop processor! The 12th generation of desktop processors will support ddr5 memory, and the memory frequency can reach more than 8000MHz. With such a high memory frequency, the memory controller of Intel processor may not support ddr5 memory. Designing such a memory frequency division mechanism can better match the use of high-frequency memory. Of course, this is only my guess.
