The bottleneck is something that is talked about a lot among users of pc, and to put them in context, first I am going to explain a little about what this is about.
He “bottleneck» on PC hardware, also known as bottle neck, is a phenomenon in which a particular component limits the total performance of the system. In other words, occurs when one hardware component cannot keep up with the otherswhich slows down the entire system to the speed of that slow component.
This term is most often used in connection with the interaction between the CPU and the GPU. If the CPU can’t process data as fast as the GPU can render it, the GPU is throttled, and this is considered a bottleneck. Similarly, if the GPU is too slow for the CPU, then the CPU is waiting for the GPU to continue its work, which is also a bottleneck.
The presence of a bottleneck can significantly limit the performance of a PC, especially in resource-intensive applications and games. Therefore, it is important to balance the choice of components when building a PC. to avoid this problem as much as possible.
So a Ryzen 5 5500 creates a bottleneck?
In the comparison that you will see below, you will see tests with the Radeon RX 7600, Radeon RX 6650 XT and Radeon RX 5700 XT graphics cards, next to the Ryzen 5 5500 processorwhich is limited to PCIe Gen3.
The Radeon RX 7600 and the Radeon RX 6650 XT, use the PCIe Gen4 x8 standard, which means that if they operate under PCIe Gen3, they only exploit 8 lanes, resulting in reduced bandwidth. On the other hand, the Radeon RX 5700 XT, which operates with the PCIe Gen4 x16 standard, takes full advantage of the 16 lanes under PCIe Gen3, without this entailing a performance penalty.
RX 7600 vs RX 6650 XT vs RX 5700 XT – will Ryzen 5 5500 bottleneck?
The Radeon RX 7600 graphics card has 2,048 shaders, 128 texture mapping units (TMUs), 64 rendering units (ROPs), 32 ray tracing cores, 128-bit bus, 8 GB of GDDR6 memory, and 32 MB of Infinity. Cache, all powered by the RDNA3 architecture. For his part, the Radeon RX 6650 XT, which has the same specifications as the RX 7600, It is based on the RDNA2 architecture. The Radeon RX 5700 XT, equipped with the RDNA architecture, has 2,560 shaders, 160 TMUs, 64 ROPs, a 256-bit bus and 8 GB of 14 GHz GDDR6 graphics memory.
It is essential not to go for more than a Radeon RX 7600
Based on the test results, the Radeon RX 7600 comes out on top with an average of 94 FPS at 1080p resolution with the Ryzen 5 5500 processor. The Radeon RX 6650 XT follows closely behind with 91 FPS, while the Radeon RX 5700 XT ranks in third position with 86 FPS. The variation compared to the performance obtained using the Ryzen 5 5600 processor turns out to be minimal, where only a slight improvement of one or two FPS is observed.
These results are surprising given that if you go for a more powerful card than these, if they are going to have a bigger performance loss when using the PCIe Gen3 standard. Also, the Ryzen 5 5600 is much more powerful than the Ryzen 5 5500. However, this minimal difference in performance is due to the fact that the graphics cards in question belong to the mid-range, rather than the high-end, which are much more applicants.
