The sluggish DIY market has slowed down hardware updates a lot, such as AMD's next-generation Ryzen processors, which will not move until the second half of this year.
Intel with the 12th generation cpu has gradually regained the point market, AMD is a hard squeeze also has to squeeze out something new.
01, the new CPU is coming soon
The price of the previous generation of products can no longer be reduced, but the next generation of products will take more than half a year.
In order to have market competitiveness in this embarrassing period, increasing the amount without increasing the price and subtracting one weight and reducing the price by three points are commonly used by manufacturers, of course, users also like this operation.
Perhaps after the 3800XT and 3900XT were educated by the market, Su Mama found that the increase was not as real as the price reduction. 5800X cut into 5700X sell 5600X price, counterpoint 12600K, can not be fragrant? These new CPUs are expected to be released this month and available next month.
They differ roughly from their original model in that they are slightly less frequent (R5-5500 cuts hyper-threading).
You can refer to 3700X and 3800X, 3600 and 3600X, good physique or good overclocking technology can make the former roughly equal to the latter.
In addition, there is a special CPU: R7 5800X3D, which will sell for $449 of the original 5800X.
This U pins the hope of the whole village, and the game demo performance is greatly improved compared to the R9 5900X.
Why does this 3D improve so much? Make the CPU a ball?
02 、 3D V-Cache
3D stacking makes better use of horizontal and vertical space, and the interconnection density is greatly improved, so it can be achieved to add several times the original cache to the existing CPU.
The success of the Ryzen processor is inseparable from its L3 Cache, and the increase in Zen2 to Zen3 has proved to be considerable by increasing the L3 cache to improve performance. It is not a new technology, in the third generation of Xiaolong EPYC processor has begun to be applied, the highest 768MB L3 cache can already be installed in the CPU Win98.
Can a consumer processor be used? The advent of the 5900X3D, which is limited to 192MB of the Jumbo L3 cache, proves to be viable.
With this "small upgrade" to deal with Intel 12-generation CPUs, it should be just right. Can mass production why not take R9-5900X to change? Why choose 5800X to make Big Brother feel bad?
03, 5800X is more suitable
Choosing to use 5800X to create the game God U, regardless of the price, there are two important reasons.
The AMD Ryzen™ CPU structure is actually very simple and clever, and the CCD where the CPU core is located and other IO-Die, such as memory, use a "glue" connection scheme.
As shown in the figure, the 5800X can be a single CCD native 8-core, while the 5900X can only be a (8-2)*2 scheme.
How much the game thread jumps back and forth between the two CCDs has an impact, and since it is going to the game, the 5800X of a single CCD is naturally more suitable.
Another reason is also obvious, dual CCDs have to paste two sets of 3D V-Cache caches.
It's not the cost of caching this bit, but now the AMD CPU heating is so serious, is the cover of two beds afraid of CPU freezing?
So the 3D V-Cache version of the 5800X is more likely to take the gaming CPU throne.
04, ordinary version is more fragrant
But after waiting so long, the result may not be so good.
Although it will not be released until next month, the AMD official website has uploaded 5800X3D parameter information, of which the turbo frequency is as low as 0.2GHz.
What is this concept? There is currently no lower desktop Ryzen™ 5000 CPU than this.
And this CPU most likely doesn't support overclocking!
In this way, the maximum turbo frequency of 4.5GHz and the 5800X of 4.7GHz start, 4.8, 4.9GHz Public level has a significant gap. The frequency and cache are one plus and one minus, and how much is improved is really difficult to say.
In terms of performance, it may take the second half of the year for Zen4 to be able to beat Intel down again.
The 5800X3D market positioning is certainly different from the regular Zen3, the release has been delayed, and the yield and heat issues may not be very optimistic. For most ordinary users, is the 5800X and 5900X after the price reduction not fragrant? Otherwise, there are new 5700X, 5600... It is difficult to talk about the cost performance intel.
