We must assume that a game is nothing more than a continuous loop in which the first part of it is carried out by the CPU or central processor. Each iteration of the loop is just one of the dozens of frames that the screen will end up showing and that our eyes see.
What benchmarks like 3DMark do is simulate the rendering of a game in a controlled environment to measure the performance of our hardware, but when we have all the identical components except for the central processor part, then it allows us to measure the computing power of the latter. and make a comparison.
In any case and before we go to the comparison between the Ryzen 9 5950X and the i9-12900K in 3DMark we have to remember that there are times when the GPU command list is generated by a single CPU core and others. For several. It is important to highlight this due to the fact that in 3D performance benchmarks based on DirectX 11 or lower the CPU is making use of only one of its cores instead of the entire set.
This is how the Ryzen 9 5950X and i9-12900K perform under 3Dmark
First of all, we must clarify that the comparison has not been made 100% under the same conditions between both processors. While the RAM in both is DDR4-3600, the mode used is Gear 1 on Intel and equivalent on AMD, the graphics card is the same in both cases, being AMD’s new RX 6600 and the monitor is a Full HD at 144 Hz and therefore the hardware is identical, given the latency problems with the AMD CPUs in Windows 11 it has been decided to do the test for el 5950X under Windows 10, while Windows 11 was used for the i9-12900K.
Starting with the performance of the AMD Ryzen 9 5950X we have to in the test CPU Simulation gets an average of 425, 6 frames per second with a minimum of 316.6 and a 533.6 maximum. This performance test measures how the load scales with the number of execution threads and in this comparison it is interesting to us due to the fact that the i9-12900K does not have 16 symmetrical cores like the 5950X.
In the second row of values we have the benchmark called CPU Render, which measures the performance of the CPU in preparing the next frame in 3D. What is measured in FPS in this case is the frequency and therefore the inverse of the time it takes the CPU to prepare each frame. In this case the value fluctuates by minimum of 184 yet 237.2 max and with a midpoint at 217.9.
Under simulation test the i9-12900K obtains 384.3 frames per second maximum, 308.4 minimum and 454.2 maximum. So we find that in this performance test the Intel CPU loses compared to that of AMD and it is a sample that the use of weaker cores and without support for multithreading becomes a bottleneck when we are facing workloads. requiring 16-core configurations.
As for the proof of CPU Render we have that the star processor of the Intel Core 12 reaches the 229 FPS Average, 194.9 minimum and 247.2 maximum. Although with these data we cannot draw conclusions, since we do not know at what clock speed these figures have been reached in the benchmark. So these are some results to be quarantined, since let’s not forget that clock speeds fluctuate in CPUs according to the workload they have. In any case, it helps us to know that the Intel Core i9-12900K are more than prepared for games in the present and future in the short and medium term, since it is still necessary for games to start demanding 32 threads of execution and not exactly few years.
