This memory speed faces a significant bottleneck.
Hello, your old PC has some interesting hardware. It runs Rampage III Extreme with an Xeon X5650 processor, 6 cores boosted to 4.2GHz. The memory setup is a bit mixed—three 2GB triple-channel DDR3 sticks and one 8GB stick—but it’s not ideal. The speed limit of 1000Mhz for the DDR3 is limiting performance, especially compared to newer systems that use faster DDR4 at around 3200Mhz. This setup definitely affects gaming and multitasking, making it feel sluggish. Compared to a brand-new PC with similar CPU power and a modern graphics card, the difference in overall performance would be noticeable.
I believe switching to a new setup with DDR4-3200 memory, a Ryzen CPU, and a B450 motherboard will bring noticeable improvements. However, it's not just the RAM that matters—your GPU might still be the limiting factor. I’m unsure exactly how much the memory is restricting performance, but overall upgrading the entire system (besides the graphics card) would pay off. About a year ago, I upgraded from a 7-year-old build to a brand-new PC for around $800. My frame rates jumped from 10 to 60 FPS, then to 100 and even 440 FPS in Minecraft. Upgrading your GPU could definitely boost performance further.
Wait for the fourth generation Ryzen, then purchase a 4600 with 16GB RAM at 3200MHz CL16 and a B506 motherboard.
Hmm, So there is more to the cpu just than clock speed and cores? I know it's an old cpu, but given the equal amount of cores/threads and on par clock frequency (after OC), compared to the AMD Ryzen 3600, it should be equal in performance no? The mobo however I do think is too causing a bottleneck.
The entire system is quite outdated, making it hard to judge just the memory and determine if it's working well or not. This only makes things worse, but DDR3 components are very affordable, so I’d consider buying two 8GB modules, stripping out the 2GB dimms, and running it at 3x8GB. You’d likely need to run some tests to check its performance, probably finding it impressive for many people. It has six cores with hyperthreading, and with a solid overclock, it could even outperform a 3770k on today’s tougher games.
I did it for fun and laughter. It outperforms a comparable 3770k by a solid gap in Cinebench R15. Check the video for the 3770k: I need to clarify, it's not a 5650 (which has 12 cores), but a 5675. My CPU achieved 923 points on the multi-core test, while in the single-core test it scored 127—clearly outmatched by the 3770k. Unfortunately, it falls short against an AMD Ryzen 2 3600 at 4200Mhz, which scores 1578.
I’m confident I’ll perform well in Cinebench, but real gaming benchmarks would offer a useful comparison with a decent GPU, particularly for titles that struggle on quad-core processors these days. My current setup uses an old X58 rig, which I still keep for sentimental reasons, but it’s now running a W3565. I’ve been considering upgrading to a 6-core processor for some time. The prices for CPUs seem a bit steep for a machine I don’t use much, though. Yes, there’s more to a CPU than just clock speed and cores—different architectural designs handle varying instruction counts per clock (IPC). For example, current Zen2 chips can outperform Intel 9/10th generation chips at similar IPC rates, while Intel manages higher clocks to compensate. In contrast, older AMD models like the Phenom sometimes lagged behind even with better clock speeds. Check out a video comparing an i7-970 and an i7-8700k at 4GHz; you’ll notice the newer chip is noticeably faster.
