Hello guys,
I am having both CPUs and thats why I am confused. I am wondering which one to keep for my self adn which one to sell on ebay.
I have an old Asus P7P55D Turbo V EVO + i7 860 and also
AsRock Z97 20th Anniversary + Pentium G3258 @ 4.7GHz.

I was wondering, which one is the better combination. What you think? The old "eight" core, or the new fast two core beast? Which one will be faster in gaming and daily stuffs? Which one will make the computer to feel faster.

I am open for your advices!

Well, the G3258 has much much better single core performance. Also has on-board graphics, though that doesn't really matter. If I'm not mistaken, it can OC to about 4.8.

The 860 doesn't have 8 real cores, but 4 with hyperthreading. Games that are gonna utilize cores the most will get more out of the pentium in this case, for having it's much stronger cores individually. The 860 only overclocks to about 4.2GHz, which for back then was good for it's price point.

Well, I am running my G3258 @ 4.7GHz and thats why I gave it as example.
The question still exist - which one will feel faster during the normal day work, and few old games from time to time. I am not talking about rendering, where definetly the i7 will pwn.

I'd still side with the pentium in this case. Much newer process, and can accompany a much nicer and more relevant mobo. Overall performance, the 860 might have a very marginal head over the pentium, but nothing noticeable by everyday task standards.

If the 860 is at stock clocks, the G3258@4.7ghz is faster in any workload, rendering included. You'd have to slap a mild overclock on the 860 (~3.2ghz) to catch up to the G3258@4.7ghz in a multi-threaded workload.

Keep in mind, the G3258 in this comparison has a near 70% clock speed advantage, and 2 architecture revisions worth of advantage on top of that. With software being compiled to take better advantage of modern architectures, the performance gap keeps getting wider. If you recall, when Bridge first came out the IPC increase was something like 20-30% over Nahalem, that lead has advanced to nearly 40% as software has improved. Haswell is sporting up to an additional 30% IPC advantage over sandy bridge era CPUs in some workloads now as compilers are optimized to leverage the additional execution resources.

Add it all up, and the G3258 is effectively 1.66(clock) X 1.8(arch) X 0.5(core count) X 0.8(HT disabled) the speed of your old 860 = 120% in a parallel workload.

Yes, todays hotrod $60 CPU is better than a $300 i7 from 5 years ago.

Granted, in older software, the architecture gains would be less as it isn't compiled to leverage the new arch very well, however, at the same time, the older software is also less apt to scale into all 8 threads proportionally, as such, the G3258@4.7ghz is going to maintain a performance advantage of near ~20% or more in almost any workload over a stock i7-860.

Dude is this even a question Pentium G3258 completely obliterates i7 860 in single thread performance and at 4,7 im pretty sure its equal even in multi threaded performance. so you got your answer sell that old #ucker

If is not for your main system, i'd stick with the pentium.

Pentium, because not only will it be near equivilant, it's probably cheaper and uses the LGA1150 motherboard rather than an old one.

Yes, but still 4 cores + HT are 4 cores + HT.
Compared even to the higher Pentium's clock speed, aren't they faster in the most daily stuffs?

There's a lot more gap than just clock speed. That's a Nahalem MicroArch CPU vs Haswell.

It's like you ignored all the posts above this last post of yours. It was already explained why the Pentium is better, read more carefully. Moar cores isn't always better, just look at AMD for a prime example of that.
