Intel's 10th generation CPU 'Comet Lake-S', which boasts a maximum clock frequency of 5.3 GHz, is on sale, is there power to fight AMD?

'

Comet Lake-S ', which is Intel's 10th generation Core processor series , was released on May 20, 2020. Starting with ' Core i9-10900K ' which adopts 14nm ++ process and boasts a maximum clock frequency of 5.3GHz , each news site has released Comet Lake-S specifications, benchmarks, and comparison results with AMD's Ryzen series. ..

Comet Lake-S adopting 14nm ++ process is CPU series for desktop, and Intel positions it as 'CPU for providing the best gaming experience'. From the Core i9 series that supports DDR4-2933 memory, Turbo Boost Max Technology 3.0, Intel Thermal Velocity Boost, 2 cores / 4 threads, base clock 4.2 GHz, but the price is 86 dollars (about 9200 yen) `` Pentium Gold G6600 It is a wide lineup. You can check the Comet Lake-S lineup and basic specifications in the following articles.

When comparing the CPU die size of Comet Lake-S with other generations, it looks like this. From the right, the size of the die increases with each generation. According to PC hardware information specialized media '

Anandtech ', the i9 series and the i7 series use 10-core dies, but the i5 series has K- and KF models with 10-core dies. The model uses a 6-core die.

In Comet Lake-S, the shape of the CPU socket has changed from LGA1151 to LGA1200, so it is necessary to prepare a new motherboard. Below is a diagram showing the structure of the Z490 chipset compatible with Comet Lake-S. PCIe is only compatible with 3.0, but we can also see steady progress such as compatibility with Intel's 2.5G Ethernet controller '

I225-V ' and Wi-Fi 6. However, it has been pointed out that the first generation I225-V silicon may not be compliant with the standard, and it seems that it may not be able to fully perform in certain environments.

Looking at the multi-threaded benchmark by Cinebench R20, the number of Comet Lake-S's high-end model `` Core i9-10900K '' represented by orange does not reach AMD's same price `` Ryzen 9 3900X '' Hmm. However, when compared to the Coffee Lake Refresh series, which also uses the 14 nm process, it can be seen that the performance has improved significantly.

Single-threaded performance doesn't seem to make much progress over the previous generation Coffee Lake Refresh. While Coffee Lake Refresh's Core i9 series has 8 cores and 16 threads, Comet Lake-S has a CPU with 10 cores and 20 threads, so it was confirmed that multi-thread performance is improved by increasing the number of cores. I can do it.

Comparing game performance between Core i9-10900K and Ryzen 9 3900X, it looks like this. The Core i9-10900K, represented by the blue bar, outperforms most titles.

This is the result of comparing the number of frames per second when encoding 1080p, 60fps video with x264 with

HandBrake . Comet Lake-S series CPUs are represented by colored bars. When comparing the same price range Core i9-10900K and Ryzen 9 3900X, Ryzen 9 3900X is winning, but performance seems to be greatly improved from the previous model Core i9-9900K. The i7 series and i5 series also show similar performance improvements from the previous models.

Next, looking at the power consumption when running the program '

y-cruncher ' that calculates the pi on a Core i9-10900K with a TDP of 125 W, the peak power consumption is 254 W.

Similarly, even for Core i7-10700K with TDP of 125 W, the maximum power consumption is 229 W, which is significantly higher than TDP.

In recent years, a

vulnerability related to speculative execution of CPU has had a great impact on Intel, and many Intel CPUs have been mitigated by firmware. Comet Lake-S says that measures are taken at the hardware and microcode level for some of these vulnerabilities.

Since Comet Lake-S inherits the structure of the Skylake generation, it can be said that 'these trends such as benchmark results are as expected.' Also, as a result of promoting optimization in the 14nm ++ process, Intel CPU is increasing the number of clocks at the expense of power consumption and that it does not support the latest functions such as PCIe 4.0 and DDR-3200 , There are negative opinions.
