Earlier this year, AMD released the second generation of X3D processors based on the Zen 4 architecture, bringing three models of Ryzen 9 7950X3D, Ryzen 9 7900X3D and Ryzen 7 7800X3D. The first two models were officially launched at 10 PM on February 28, with prices of 5,299 yuan and 4,499 yuan.
But sources say the price of the Ryzen 9 7900X3D has already been cut overseas, just a month after it went on sale.
Last year AMD launched the first 3D V-Cache design, the Ryzen 7 5800X3D, which integrates up to 64MB of 3D V-Cache stack, plus the existing 4MB level 2 cache and 32MB level 3 cache for a total of 100MB cache.
With the cache added to the game, the Ryzen 7 5800X3D had no match in game performance, and even the i9-12900KS was easily crushed.
With this industry-leading technology, the AMD Ryzen 7 5800X3D gaming processor can boost gaming performance by an average of 15% at 1080P high Settings, officials said. AMD Ryzen 7 5800X3D game processor uses 7nm manufacturing process, Zen 3 core architecture, up to 8 core 16 threads, base frequency 3.4GHz, up to 4.5GHz acceleration frequency.
The new generation of three processors using 3D V-Cache is a complete upgrade. The Ryzen 9 7900X3D is 300MHz lower than the default frequency of the Ryzen 9 7900X at 4.4GHz, but the acceleration rate remains consistent at 5.6GHz. In terms of cache, it also has 12 MB second-level cache, 64MB third-level cache, and 64MB 3D V-Cache cache, a total of 140MB of super cache.
AMD is also using a heterogeneous design for the Ryzen 7000X3D model, but not the same as Intel's Core processor. Instead of using small and large cores, AMD has equipped eight of the original 16 cores with 3D V-cache technology, and the other eight are normal cores for high-cache scenarios and high-frequency scenarios.
However, the scheduling problem of heterogeneous design processors has always affected the actual user experience. Although Intel Core has made great progress in energy efficiency and performance by relying on heterogeneous processors, the chaos of scheduling strategy in the actual use of Windows system has also put Winter Alliance under suspicion.
This is the fate of the Winter Alliance, not to mention AMD? So instead of giving Windows the responsibility for scheduling at all, AMD has its own chipset drivers that dynamically assign which kernel Windows uses. If a cache sensitive usage scenario is encountered, AMD drivers will drive Windows to call the core equipped with 3D V-Cache technology, and if a frequency sensitive scenario is encountered, the high frequency core is called more frequently.
In this way, AMD Ryzen 7000X3D solves the scheduling problem well, and under the premise of ensuring the game performance, it has a good professional performance. Both ways balance the energy consumption problem, which can be described as three birds with one stone.
For AMD Ryzen 9 7900X3D, in the game performance is greatly improved at the same time, but also in the basic performance of the wind, should be welcomed by the player group. However, this processor has been reduced to 585 US dollars abroad, equivalent to about 4,000 yuan, compared to 4,499 yuan in China has a price reduction of nearly 500 yuan.
The reason is, on the one hand, the new processor has just come on the market, the price is high, especially the price of the supporting motherboard is high, and the cost of replacing the player is too high. On the other hand, foreign players are generally used to playing games with consoles, so the market size of game PC is not large, compared with the domestic market is relatively small, under the dual reasons, overseas will take measures to promote sales.
In China, due to the strong demand for games, the price is still maintained at the original price.
