Games themselves also are contributing factors why we get CPU or GPU bottleneck. You may think that it’s either you just have a slow processor or a poor graphics card that causes it. Now let’s talk about what really causes a CPU and a GPU to bottleneck. MORE: Best Graphics Cards Causes of CPU and GPU Bottleneck It processes so fast that the GT 1030 just doesn’t have the speed to return the processed data back. Without a doubt, the Core i7 processor can process games fast. Let’s take an Intel Core i7-8700K processor and pair it with a GT 1030 graphics card. The same concept applies to GPU bottleneck – only this happens if you pair a fast processor with an entry level graphics card. See the image below for a better visual representation of what’s happening when a CPU bottlenecks.Ī solution to balance out the processing speeds can be made by adjusting resolutions – we’ll have this covered later in detail. A bottleneck happens if the speed of data transfer is capped. The CPU is what’s responsible for processing real-time game actions, physics, UI, audio and other complex CPU-bound processes. However, because the A6 processor can’t keep up with the processing speed of the graphics card, CPU bottleneck happens. On paper, a GTX 1080 Ti can easily run games with improved graphics details. CPU BottleneckĬPU bottleneck happens when the processor isn’t fast enough to process and transfer data.Ī good example of which is to look at an AMD A6 5th gen processor paired with a GTX 1080 Ti graphics card. We’ll talk more about the details of the processes later. If they have huge differences in processing speed, bottleneck will happen. The components that are involved in the process of bottlenecking are the CPU (processor) and the GPU (graphics card). In other words, this means that the capacity to return a processed data is not enough compared to how much data is being sent for processing. This massive boost in frame rate can even be seen at 1440p as the R5 1600 allows Vega 64 to push well beyond 60 fps at all times, impressive stuff indeed.Defining Bottleneck, CPU Bottleneck and GPU Bottleneckīottleneck, as for how it is named, occurs when there is a limit on how much data is being sent for processing or how much data can be processed at the same time. However, Vega 64 is now 15% faster for the average frame rate and a whopping 21% faster for the 1% low result.
The GTX 1080 is capable of basically the same numbers we saw when testing with the 7700K. However, throw both the GTX 1080 and Vega 64 graphics cards on the Ryand we find a different story. Vega's superior DX12 support appears hampered by the Core i7-7700K's limited cores and as a result Vega 64 is actually seen to be slower than the GTX 1080 at 1080p. What was just seen when testing with Ashes of the Singularity is somewhat amplified in Civilization VI.
Vega's superior DX12 support is certainly allowing Ryzen to shine here, at least this is my interpretation of the results. This is also seen when using the GTX 1080, though to a much lesser degree. The R5 1600 and its many threads is still able to get the most out of the Vega 64 GPU and is now quite a bit faster than the GTX 1080. Moving to 1440p load begins to shift more towards the GPU but we do see something of note. The 7700K and R5 1600 appear evenly matched under heavy usage scenarios in games as they can be seen delivering similar performance.

Anyway, using DX12 we do see some interesting things.įirst, at 1080p we are mostly CPU limited I'd say. Using the GTX 1080 though we see that Ryzen is indeed now competitive.Īshes of the Singularity was tested using DirectX 12 and no I haven't had time to explore how the game behaves with Vulkan yet. Increasing the resolution to 1440p we see the R5 1600 struggling with Vega 64, again the 1% low result is particularly troubling. Meanwhile, with the GTX 1080 installed the R5 1600 is competitive with the 7700K. Interestingly, with Vega 64 running at 1080p we saw the R5 1600 struggle quite a bit, significantly more than the 7700K. The last of the DirectX 11 titles tested is Ghost Recon Wildlands and here we again see competitive performance for the most part. Ghost Recon Wildlands, Ashes of the Singularity, Civilization VI
