What impact will the GPU have on the CPU performance?
I'm considering upgrading to a Geforce GTX 1650 OC or GAMING X with 4GB RAM but I have an i5-2500 processor instead of a K. I'm unsure if I should opt for either of these GPUs or the RX 570, especially since I want to avoid overclocking the CPU too much. Will the 1650 affect the CPU performance significantly? Should I choose the RX 570 or go with the 1650?
(Also, I'm planning a budget build because I don't have much money for a complete new setup and I'm reusing my existing CPU, RAM, and HDD from my HP Compaq 6200 SFF Pro. Just because I bought a new case, cooler, and PSU doesn't mean you should be discouraged about your choice since I wasn't sure what components to use at the time.)
As described in the poster, the RX570 performs roughly 10% better than the 1650. If you're looking for an improved graphics card, consider models like the RX590 or similar. Also, think about upgrading your CPU, memory, and motherboard later on, since otherwise the CPU might become a limiting factor.
A cpu cannot ever become a bottleneck; that idea is misleading and not used properly. Source provides data to the cpu, which processes it into frames and sends them to the gpu. The gpu then creates the final image based on resolution and detail settings. If the cpu can handle 60 frames per second, the gpu receives those frames regardless of its speed. Whether the gpu can display them depends on its capabilities, not the cpu's performance. A bottleneck occurs when a component restricts data flow, like a clogged pipe. Since the cpu generates all FPS and the gpu doesn’t influence it, it’s impossible for the cpu to act as a bottleneck. The main impact of an overpowered gpu is maximizing detail at any resolution, which may not improve performance in older games or lower settings. A more powerful gpu won’t raise FPS but will enhance picture quality and detail without affecting screen numbers. A less capable gpu might struggle to show details if set too high. Choose the best GPU you can afford—it won’t hinder the cpu, even if it doesn’t run at full capacity in some titles.
It's intended as a budget build since I have limited funds and don't want to spend another 200 just for a system, even though I already paid for something that seemed pre-optimized for gaming. I'm just trying to decide which one to purchase.
I've been working with PCs from 1980 onward, raised four children, own my home, and am still married. There are many people here with similar experiences and a deeper understanding of PCs than I do. They are all volunteers. So when someone offers you help or advice that doesn't fit your needs, it's best to simply say thank you.
I believe people are referring to the idea of a bottleneck, meaning one part is limiting the performance of another. For example, if a game is very CPU-intensive and uses an older CPU, it could prevent the graphics card from working at its full capacity. With a CPU, it’s like an upside-down bottle where water slowly flows in, whereas with a weaker GPU, it’s more like water slowly leaking out because of a smaller opening.
To address this, it’s best to get the top GPU you can afford so you can upgrade later.
