AMD 3950X has long been the flagship product for many workstations around the world, but the new 5950X is leading something different.

Although it still has all the qualities used in a workstation, it also has impressive gaming performance. Let's take a look at these two CPUs together and see which one is the best.

requires a CPU cooler

, take a look at 5950X CPU cooler. . These two AMD

models are very popular on their own, but do upgrades always mean better? Let's find out.

AMD uses "Zen" instead of the usual "Gen", which stands for generation. 3950X adopts Zen second, while 5950X is based on Zen 3. Both of these Zen architectures use the 7nm process; however, there are significant differences between the two CPUs. Compared with Zen 2,

AMD pays more attention to improving technology in the Zen 3 architecture. The IPC and power efficiency of the Zen 3 model are greatly improved, which means that these are the two benefits of the 5950X. The improved architecture of

is generally welcomed by enthusiasts, and the Zen 3 model is also well received by users. Although Zen 2 was impressive when it was released, why not adopt a newer, more advanced architecture?

Earlier we mentioned that both 3950X and 5950X have 16 cores, but we still do not deny that they are composed of a cache part. The former has four 16MB cache sections, each with four cores, while the second has two 32MB cache slices, each with eight cores.

Therefore, although the number of cores and memory of the two CPUs is the same, the efficiency of the two models is quite different. The impact of the cache part is more than you initially thought. The four cores of the

5950X can access L3 memory. Now you can have 8 cores accessing the large memory pool at the same time instead of the 5950X.

can access large memory pools without having to jump between different cache segments, which can save time and annoy gamers. This will also reduce the lag of the game to less lag after placing an order. The

5950X obviously has an advantage in this regard, because it has the potential to run your games faster than the 3950X.

In the specs, we have set the base frequency and the turbo frequency of the CPU that we are comparing today. The base frequency

is related to the normal operating point of the CPU, while the turbo frequency implies the maximum speed that the processor can achieve. The higher the base frequency and the turbo frequency of the CPU

, the faster the clock speed. Although a faster clock speed generally means a faster CPU, there are several factors that can affect this. The base frequency of the 3950X is 3.5GHz, which means that the CPU runs 3.5 billion cycles per second. In contrast to

, the 5950X base frequency is 3.4GHz. However, don't worry about the slight drop in frequency for now. The more efficient core of this CPU will compensate for the slight drop in frequency.

More importantly, the 5950X turbo frequency is more impressive than the 3950X.

Although the turbo frequency of the newer model is 4.9 GHz, the turbo frequency of the 3950X is only 4.7 GHz. It is better to let your CPU run at a slower speed to avoid overheating, but a blanket of turbo safety is beneficial.

games require your CPU to have a lot of impressive features to run as smoothly as possible, so frequency is no longer the only feature a gaming CPU should look for. However, the frequency must be high enough to work with the smart core and architecture. The

3950X and 5950X memory types are DDR43200. The first part of this type means "double data rate", the higher the number, the faster the memory.

bandwidth is also higher. Since the two CPUs we compared are both DDR4 memory, the code name is the fourth generation.

3200 refers to the CPU data transfer rate per second, in millions. This is impressive in itself, with a maximum transfer rate of 25,600MB per second. DDR4 memory type is suitable for users who want to make full use of the system, provide faster speed and better response.

These are most suitable for professional gamers and designers, so in terms of memory, both 3950X and 5950X can be used for games. You don't need to wait for the game to load, the delay will be kept to a minimum.

When we think of memory, we think of the information contained in the CPU. However, there are also memory components that exceed this limit, which encode and retrieve data

The memory of the 3950X and 5950X will surprise you, whether it's a game or any purpose you decide to use your computer for.

Since its launch in 2019, the 3950X has quickly become one of the most widely used CPUs for computer-based creative entrepreneurs. Twitch anchors, video editors, and Youtubers already use this CPU to improve their computer performance so that they can make the most of their time. The high number of

cores and impressive memory are additional advantages for 3950X users, not to mention the relatively low price of this caliber CPU. The newer 5950X has all of these same features, so it performs as well as the 3950X in workstation tasks. Both

3950X and 5950X are considered high-end CPUs with high ratings and customer satisfaction. However, if you are considering choosing one of these CPUs for your game, you may not be interested in the workload performance. Instead, we use benchmark software to help us understand the performance of these two CPUs in games.

Geekbench 4 is a platform for testing the CPU in many different ways, such as imaging, data compression, 3D object simulation, photo editing, SQL encoding, PDF file rendering, fast Fourier transform, and matrix calculation.

3950X and 5950X CPU usage on a Windows computer shows that on a single core, there is a 23% difference between the two. However, on multiple cores, there is only a 1% difference. Similarly, running them on macOS shows a single-core difference of 57% and a multi-core difference of 34%.

Although more and more games begin to use multi-core processing power, most of them still use single-core processors. 5950X has the best of both worlds in terms of processing power, so you can use it for games and heavier tasks. An interesting difference between the

3950X and 5950X CPUs is that the latter is 20 mm longer than the former. This difference will certainly please gamers who are not looking for laggard CPUs in the market. If you are looking for a fast CPU to run various games, we think the 5090X is a good choice.

AMD itself published statistics on gaming performance between the 3950X and 5950X CPUs, showing that the latter is between 14% and 29% higher than the former in the performance of four different games.

Although this is interesting and can give you an idea of which CPU may be more suitable for gaming, it can also be an upsell strategy for AMD to promote their new CPU.

Given that the 5950X CPU is the newer model of the two, it's not surprising that its price is roughly $ 70 higher than the 3950X.

But the price is not much different, so when comparing the price and performance, the two CPUs are comparable.

So it is up to you whether you decide to choose a newer model. It is worth noting that the cost per frame for 3950X is $ 0.079, while the cost per frame for 5950X is $ 0.078. Although the difference of $ 0.0001 doesn't seem like much, in the long run, it all adds up!

At the time of writing, the 3950X has a large inventory on Amazon, but the 5950X CPU is not currently available on the platform. Although you can buy it elsewhere on the internet, this may demonstrate how popular the newer CPU models are.

Although the 5950X is not currently available on Amazon, we believe it will be available soon, so pay attention.

We suggest that you do not wait too long before buying it because it is already out of stock. The 3950X is still available, but we don't know how long this situation will last.

With the newer CPUs on the market, we assume the 5950X will be easier to obtain. However, since it was released recently, many people are very happy to be able to get in touch with it.

In general, we believe that AMD has surpassed itself on 3950X and 5950X CPUs. Both are excellently constructed in their own way and are very attractively priced for most gamers.

Although the newer 5950X has some more advanced features, such as the cache section and Turbo frequency, the 3950X is still an excellent competitor. The

two CPUs have similar memory and slots, but the 3950X is usually used in workstations and gaming settings. The basic clock of this CPU is slightly faster than that of the 5950X, but the turbo clock of the 5950X is even more impressive. The unique memory settings in the

5950X can certainly make up for the slight drop in base frequency. All in all, we think all the signs indicate that the 5950X is the most suitable CPU for gamers.

With that said, if you buy a cheaper model on the market, the 3950X is still a respected model.
