Comparing an overclocked i5 750 at 4GHz to a modern i7 would depend on the specific models and conditions.
Comparing an overclocked i5 750 at 4GHz to a modern i7 would depend on the specific models and conditions.
Hi,
I'm setting up a gaming rig and I'm considering getting an older processor. It seems the graphics card I want (R9290 Vapor X) might be limited by this one (i5 750). I was wondering if I could overclock it to above 4 GHz—there are reports it can reach around 4.7 GHz. If you think it's feasible, let me know the steps. Also, if you expect it to hit speeds near the i7 range, please share your thoughts.
I'm not too concerned about heat or power because I'll also have a 650-watt platinum PSU and a Corsair H75 hydro cooler. I prefer using the same CPU since it's affordable and I'm confident it can meet my needs—my only concern is whether it will actually be a bottleneck.
Thanks a lot,
Ali
Realistically, the CPU speeds of all components except the Z170 socket are only about 25% faster than the first-gen I7 45nm Nehalem processors released in 2008 when compared to the 4790K. A maximum of 4.5GHz is 25% slower than the 4.5GHz 4770K. Performance differences like 2600k, 3770k, and 4770K are mainly clock-based only.
Even with a consistent 4.7 GHz, it's unlikely you'll match today's i7 performance. You might get results similar to a more recent i5. I don't have experience with overclocking older Intel chips, so I can't share that advice.
even if you achieve a steady 4.7 GHz, I question whether you'll reach performance levels similar to a contemporary i7. You might experience performance that's only slightly better than a more recent i5. I don't have direct experience with overclocking older Intel chips, so I can't offer advice on that. Thank you very much for your assistance—I hope you consider trying another processor.
in terms of performance the i3 750 matches the capabilities of the i7 intel 4460, though its second generation nearleg suggests a maximum clock speed around 4.8ghz. with water cooling it could reach i7 920 at 3.5ghz or an i5 4460 delivering performance equivalent to a clock per clock. alternatively, a bone stock i7 4690k turbo at 3.5ghz would work well. the socket type differs, but these configurations have proven stable with a 45nm i7 920 @ 4.5ghz, and a 4.8ghz x5675 32nm, which should suit the 750 i5 32nm @ 4.6ghz.
A first generation i5 cannot match a contemporary i7 in any way or form.
Comparing the two shows a modern i7 is 48% to 138% quicker, consumes less energy, and stays cooler. Choosing such an outdated processor is completely unnecessary.
