Amd ryzen 5900x vs 3900x zen 3 vs zen 2

Proper workstation equipment, we recommend that you check out the 16-core 5950X or, if your budget is tight, consider using a second-hand 3950X. The exception is if you are only interested in the performance of software like Adobe Photoshop, which relies primarily on single-core speed rather than multi-core usage. For most other visual effects and editing programs and streaming media usage, 5950X is your best choice. However, when comparing the 5900X and 3900X for workstation purposes, the 5900X is definitely among the best.

At first glance, you may notice that the base clock speed of the 5900X is actually slightly lower than that of the 3900X. Although this may seem counterintuitive at first, clock speed is only part of the performance story. Previous architectural enhancements mean that the 5900X's Instructions Per Clock (IPC) has increased significantly, so the total number of CPU instructions can exceed at any given time.

Although newer games are beginning to take advantage of multiprocessor capabilities, and this trend may increase, the important metric in games is still single-core performance. Single-core (or even threaded) performance is also an important consideration for certain applications like Adobe Photoshop. The goal of the AMD 5900X is to create a CPU that can handle heavy multi-core tasks like the 3900X and provide single-core gaming capabilities. In theory, the newer models should be superior to the Zen 2 processors in this regard.

In the initial presentation, AMD stated that the overall performance of the Zen 2 and Zen 3 has increased by approximately 19%. Let's take a look at the latest benchmark test and see how real this is.

At first glance, you may notice that the base clock speed of the 5900X is actually slightly lower than that of the 3900X. Although this may seem counterintuitive at first, clock speed is only part of the performance story. The above architectural improvements mean that the 5900X's instructions per clock (IPC) are significantly higher, so the total number of instructions of the CPU can do in a given time. Things are bigger.

Although newer games start to use multiple processors, and this trend may increase, the important indicator of games is still single-core performance. Single-core performance (even threaded processing) is also the top consideration in certain applications such as Adobe Photoshop. The goal of AMD 5900X is to create a CPU that can perform as many multi-core overloads as the 3900X, but theoretically also has single-core gaming capabilities, so the newer model should outperform the Zen 2 processor. There is a certain gap in this area. .

From the above FPS results, it is obvious that AMD’s statement seems to be very profitable. In fact, between 3900XT and 5900XT, at least in the games currently tested, the performance improvement is underestimated anyway. The average FPS of "Tomb Raider: Shadow" has increased by 25%, the Microsoft Flight Simulator (the famous CPU heavy game) has increased by 22%, and the average FPS of CS:GO has increased by 30%. Given the 18% price difference between the two processors (assuming the 3900X is still $464), in our opinion, the 5900X represents a huge value. This is especially true if you are considering buying a new Radeon 6000 series graphics card, as we will see below.

The last thing to consider when comparing 3900X and 5900X is whether you plan to buy one of AMD’s new Radeon 6000 series graphics cards. As discussed in more detail here, the intelligent memory access function enables Ryzen 5000 series CPUs to obtain additional performance by using GPU memory more efficiently. In the games AMD showed us, the additional FPS performance increased by 2 % To 13%. Once the new Radeon graphics card is released, we will better understand how true this is, but so far AMD’s other performance claims have proven to be true.

Note that the FPS gain between 5900X and 3900X shown in the benchmark chart above does not take into account Smart Access memory, so if you plan to buy a Radeon card anyway, this basically means performance additional free. In fact, if the AMD 6000 series GPU is paired with the new 3900X CPU, anyone who can buy an AMD 6000 series GPU will really miss out; in this case, the 5900X will be the obvious choice.

The last thing to consider when comparing the 3900X and 5900X is if you plan to buy a new Radeon 6000 series graphics card from AMD. As discussed here, in more detail, the Smart Memory Access feature allows Ryzen 5000 series CPUs to get extra performance by using GPU memory more efficiently.In the games that AMD showed us, the range performance is between 2% and 13 times the FPS. Once the new Radeon graphics card is released, we will better understand its authenticity, but so far AMD's other performance claims have been proven to be true.

All aspects of performance, 5900X is the best

Game performance, sometimes more depends on the game, and the huge improvement in workstation usage. If you buy a new graphics card, then the 5900X is the obvious choice. If you also buy a Radeon 6000 series graphics card, then the decision is even more obvious, although if the second-hand price of the 3900X drops significantly and your budget is tight, this may It is also worth considering.

If you already own a 3900X, then the question is, is the approximately 20% 25% increase in FPS performance worth $549 to you (not including any additional smart memory access rewards)? Selling your current 3900X on the second-hand market can certainly reduce the net impact on your wallet. If you buy a new Radeon 6000 series graphics card, they provide additional SAM performance and future-oriented performance. Sweeten the transaction.

Allinall, 5900X is significantly better than its predecessor CPU, this is an example of our belief that the intergenerational improvement is definitely worth the money.
