new processors AMD Ryzen 9 7950X it was released last month and brought the Zen 4 architecture and compatibility with DDR5 and PCIe 5.0 memory. Intel has already adopted these technologies in the past generation and will expand its product line with new technologies next week. Core i9-13900K.

The 13th generation Intel is coming October 20, including in Brazil, and is already on pre-sale in select retail stores. To make life easier for users who want to update their systems, TecMundo He prepared a questionnaire comparing the results. new Raptor Lake CPUs with new arrivals AMD Ryzen 9 7000 in synthetic tests.

Ryzen 9 7950X and Core i9-13900K Specifications

Intel processors Core i9-13900K Raptor Lake It’s the evolution of Alder Lake and brings the same features that were featured last year. The main one is the hybrid 32-core system.

Intel’s new flagship has 16 cores predator sheep (P) performance-oriented and 8-core gracemont (e) is geared towards processing efficiency and low consumption. Since it is only compatible with P cores hyper threadingThe 13900K also has the same 32 threads. Ryzen 9 7950XAlthough it has 8 cores.

Hybrid core technology also directly affects the frequencies and cache of new Intel chips. basic clock Intel Core i9 It is 3 GHz for Raptor Cove cores and 2.2 GHz for Gracemont cores. Boost frequencies are 5.4 GHz and 4.3 GHz respectively, and this combination results in a thermal design (TDP) of just 125W.

Although it only has 36MB of L3 cache compared to 64MB of cache 7950Xjoyful i9-13900K Bring 16MB of L2 cache for each core group, for a total of 32MB. In addition, the processor’s L3 memory uses the new Intel Smart Cache technology, which optimizes its performance.

In terms of energy consumption, it is important to note that even with a lower thermal design: Ryzen 9Intel CPUs run at 253W with a 1-second boost system that raises frequencies up to the processor thermal limit of up to 5.8 GHz (P) at the cores.

preliminary tests

Most of the new tests i9-13900k The ones announced so far bring unconfirmed results as they use non-commercial models. However, considering that these are not engineering examples, the official figures should not differ much from those obtained so far.

Because it is a current implementation of the core architecture big small The next generation adopted by Intel with Alder Lake naturally brings superior performance. However, it is not much different from the new one. Ryzen 9 7950X and 7900X.

In multi-core test Geekbench 5 64bit is only 1% ahead of 7950X, 13900K. While the result isn’t ideal for Intel’s new CPU, multi-threaded has always been AMD’s area of ​​expertise.

Performance per core is the only test that shows the i9-13000 series has a significant advantage over the new Ryzen 9.

The small advantage of AMD’s enthusiast processor is also Geekbench 5 single core and Cinebench R20 multicorei9 only Cinebench R20 single core, with a margin of 10%. This difference was most likely the result of the device’s 5.8 GHz frequency. 13900K operates at its thermal limit.

A technical link using a hybrid core standard that’s just new in desktop PCs suggests a more positive estimate for the new Raptor Lake, especially since it only achieves these numbers with a 125W thermal design.

Core i9-13900K performance dependent but more energy efficient than Ryzen 9 7950X

Although more energy efficient than AMD processors, Intel’s new series also implemented an operating standard aimed at operating close to the thermal limit. In this way as well Ryzen 9HE core i9 it also requires a robust cooling kit and does not come with its own thermal solution.

price per performance

The biggest difference between the new high-end CPUs is their suggested market price. HE Core i9-13900K Pre-sale at a fixed retail price of R$ 4,699.99, Ryzen 9 7950X ranges from R$5,499.00 (recommended price) to R$6,232.90 depending on the store.

The Core i9-13900K is still available for pre-order at MSRP, while the Ryzen 9 7950X is already starting to appear bloated in markets.

Another advantage of Intel’s CPU is, Ryzen 7000Compatible with Z690 motherboards with next-generation DDR4 memory, it’s still considered transitional. In addition to the prices of these models, which have already dropped since their release in 2021, the maintenance of DDR4 memory kits makes the system upgrade cheaper.

This same factor represents an advantage even with respect to the following. Ryzen 9 7900X. While these models have a suggested price of R$4,199.99 and their performance is close to the new i9, adopting an AMD CPU necessarily requires purchasing DDR5 memory.

Apparently, new processors Ryzen 9 It outperforms Intel’s 13th generation. However, in addition to the higher AMD installation investment, Intel’s bet on hybrid cores still has strong potential to outperform the new Zen 4 architecture in the long run.
