Best Generation 5 CPU for gaming

[September_90]

Hi all. Im looking for a 2nd opinion on which processor to buy.

I began upgrading my pc last year, and never got round to changing my CPU, although I could probably do with getting a new motherboard altogether, so that I can get a gen 6 or 7 CPU in the long run, but for now Im just going to upgrade from gen 4 to 5, and I hope from an I5 to an I7, if it is agreeable, to try get the most from my graphics card and for a better gaming experience, for the next however many years.

Anyway, this is my current build.

I5 4670 cpu. (I plan on changing this)
MSI Z97-5 mobo.
MSI R9 390 8GB gpu.
850W psu.
32GB Ram.

I need a new cpu to at least get more from my graphics card, as the current one is bottlenecked, and I play a lot of online gaming such as Civilisation, Total war etc, so they can be quite taxing in online multiplayer on the cpu.

I cant decide weather I5 or I7 but the I7s do seem slightly better.

I am leaning towards the i7, 5775R 3.3 GHz. However there is not much between this and the I7 5775C 3.3 GHz but I could use a second opinion. Or even a better suggestion for a gen 5

Thanks!

Broadwell had an extremely limited desktop release. I think the 'R' CPUs are BGA and are only sold integrated onto motherboards already. Your only two real Broadwell options are the i5 5675C and i7 5775C, both of which are rather pricey due to their large L4 cache and Iris Pro IGPs. Generally speaking, your best upgrade option without a motherboard swap is the i7 4790k. There might be a few titles out here and there where the 5775C might pull ahead due to the massive L4 cache, but probably not enough to make it worth the huge price premium.

That cpu is going to cost a lot. Better idea would be an i7 4770k or 4790k. That would be if you want to stick with the same motherboard and ram. The step up as far an i5 would be the 6600k. but that would mean new ram and motherboard.

^ a 4790k seems to be the best option here.

Thanks I didn't realise they were BGA. The i7-5775C seems to have everything I want, a good amount of threads, cache and a larger maximum graphics memory. Everything else is decent enough.

I don't mind the price as Iv worked a fair bit of overtime to pay for a new CPU. Eventually I will sell it on and upgrade the mobo but for now something like this is good enough I think.

You're not using the integrated graphics at all if you have a discrete GPU. Desktop Broadwell would be wasted on that - it was meant to have strong integrated graphics with Haswell-level performance.

The 4790k is an excellent performer and is pretty much what you'd be looking for.

The I7-4790k, does seem very tempting. Some benefits, and a larger cache, older, which probably makes it cheaper I would think.

It comes down to which would get the most out of my graphics card, and which would handle the most amount of FPS and the calculations in some of the more complex games, which can be very demanding, I suppose you could compare it to doing spread sheets.

Would the more logical threads in the 5776 be better than the less in the 4790 for what im after?

5675/5775C have the same # of threads as any 4-core i7 - 4-core/8T.

The 4790K has a higher stock clock, and they respond well to overclocks as well. I believe the Broadwell chips are also unlocked, but I'm not sure how well they do actually overclock as very few actually owned them. Broadwell was eseentially just a die shrink of Haswell - same architecture, slightly more power-efficient.

The 4790k is within <10% of the performance of a modern i7-7700k at equal clock speeds. Not too shabby IMO. The Broadwell chips, if my memory serves correctly, only have a 3% increase in intstructions per clock (most of it was focused on power efficiency, heat dissipation, and the internal graphics being way better than before).

Maybe I should look to get the 5776 for the L4 cache? which has a lower cache of 6 MB, instead of the 8 MB SmartCache of the 4790, perhaps the latency is greater in this, and I would have a better performance with the 5776?

The 5775C and 4790k have the same number of cores and threads. The big difference between them is the 5775C has a much better IGP which is useless when you have a dedicated graphics card and has a large L4 cache, the 5775C is also a poorer overclocker and has a considerably lower stock clock speed than the 4790k.

For most games, you are better off with the 4790k as the IGP is useless to you and the L4 cache isn't hugely beneficial in every title. Most of the time the 5775C gets about equal performance in games to the 4790k, the L4 cache helps offset the lower clockspeeds a bit, but it doesn't really make it faster given that the 5775C isn't a great overclocker and won't achieve the same high clocks the 4790k can.

Its possible that the L4 cache will be preferable and beneficial instead of the higher clock speed but I cant find any information on the games I play to suggest that this would be the case.

Sadly there aren't a huge number of benchmarks for the 5775C, most sites didn't bother covering it beyond it's initial release as the chip was so rare to find in retail and was massively overpriced.

Im looking online at the price, the 5775 is actually cheaper haha, when I thought I had it all decided.... only for a preowned model, Im going for the 4790K. Thanks guys

Many I5's and I7's are being pushed to their limits in today's titles. They are being pushed to 100% and are being CPU-bound! Personally, higher FPS isn't what you really want rather you are looking for high 0.1% and 1% minimums which can cause the FPS spikes you are experiencing with quad cores. The 1600 goes for $209.99 on amazon and comes with a CPU cooler, which is capable of 3.7GHz overclock. Spend ~$30 for a Evo 212 cooler, and you can hit 3.9-4.1GHz. Because of infinity fabric and the latest AGESA you will get significantly higher RAM compatibility. It has been shown that changing from 2333MHz RAM to 3200MHz RAM can give you ~30% increase in FPS in memory intensive games. Infinity Fabric uses RAM speed as it's reference close, so high speed RAM reduces inter CCX communication latency. Unless you are using a an extremely powerful GPU 1080Ti you will likely be GPU bound, and the performance difference between Ryzen and Intel at 1080p is within 10FPS averages and within 5FPS minimums in most gaming scenarios. This is a link I found to the latest benchmarks, but it's in a German. You can still read the numbers. http://www.gamestar.de/artikel/amd-ryzen-5-1600-zu-recht-der-beliebteste-sechskerner,3315661,seite2.html Shows Ryzen

I bought the I7 4790K, got it delivered next day for free, I waited in all day for the evening delivery, and the fucking chip wasn't even in the box, now I have to wait all weekend for a refund, but first I need to repost the original item before they can process it. so annoying
