Too slow for modeling tasks
Too slow for modeling tasks
Hi, I have a 4690K with beQuiet D.R. 3 and an XPS15 with a 9750 I'm running a lot of Abaqus and other FEA simulations for university lately and even tho I obv expected the i7 to be quite a lot better at it then the i5, the difference is MASSIVE. I though thermal limitations on the laptop and the overclock capabilities of the i5 would have compensated just a little but looks like no, the i5 looks like it doesen't almost want to run them, even "light" ones. Now I ask you, can I do something to make i5 at least useful? I don't really like the i7 having to run 100% at 100°C for 10 hours or more, I hoped I could make the other one do the hard work, even spending twice the time maybe... Does buying an used i7 4790 K or not, make any sense, can it get as good as the i7? Thanks for any suggestion you will give me, have a nice day
The 9750H represents a significant advancement over the 4790K. Adding two extra cores and using more modern architecture makes it difficult to dismiss, particularly given the relatively high prices in the used market.
The i5 might not be sufficient or FEA analyses suggest the mesh size is probably too small, or the software doesn't recognize it as a 4-core processor. Demands grow rapidly as the mesh gets finer. Using the 4790K could only boost performance by about 60% at its best compared to the 4690K.
The investment already includes the laptop, which is a substantial purchase. Ryzen offers good performance for its price, but it will be expensive because you'll need to replace the CPU, motherboard, and RAM. You're wondering about a suitable budget mix for CPU, motherboard, and RAM together. You're thinking of either maintaining your current CPU setup or switching to an AMD version, possibly changing the architecture. Yes, you want to simulate on the laptop or transition to a different design. For benchmarking, it's important to use reliable tests to compare CPUs effectively. Let me know if you need more details!
Use the laptop for troubleshooting. It’s simple to resolve the overheating problems. Purchase good thermal paste, disassemble the device, and reapply the CPU paste. This should bring temperatures down to around 85-90°C. Another option is to lower the clock speed of the 9750h by a small amount. Running at 90% of its normal frequency with two extra cores will still cause overheating for a 4770k or even a 4570k.
Thanks for the suggestion, but I’m not sure I agree with the simple explanation. Changing things would mean risking warranty validity, which is quite dangerous. I’ve started using throttlestop now and am trying to learn how to boost performance without overheating—especially since 100°C for 16 hours isn’t ideal.
If you're concerned about the warranty, try running the CPU at 100°C until it fails or just before the warranty ends and request a replacement by mentioning it's overheating. I didn't consider the warranty at first.
I mostly purchase refurbished components and used computers, so it usually doesn't impact me much. Hopefully, it's lucky—I haven't experienced a part failure before buying it (a cheap GPU deal I thought had driver problems turned out fine). That said, I did accidentally damage a motherboard because I miscalculated the voltage settings.
