core i5's --- 4460 vs 4590 - pci express 2.0 vs 3.0?

[TheDarkKnight]

I am confused about how much of a benefit pci express 3.0 over pci express 2.0 would be when using *ONLY* the iGPU, i.e. the integrated HD4600 Intel Graphics.

I initially thought that the 4460 was a no-brainer since it comes with a megabyte of L2 cache and the 4590 has zero L2 cache.

The only thing that is making me second guess myself if that it *appears* that the i5-4460 is limited to pci-e 2.0 and the 4590 would be capable of pci-e 3.0. Does this mean fairly large performance gains using the HD4600 on the 4590? Or is the HD4600 integrated graphics even capable of saturating the pci-e 2.0 bus?

Bang for buck I think I am gonna go with the 4460 over the 4590 unless somebody gives me a good reason not too.

Thanks for reading!

Edit: Just to ask it another way, does the PCI-E 2.0 versus PCI-E 3.0 capabilities come into play for integrated graphics at all or is it only a factor when using discrete graphics cards?

The HD4600 doesnt use the PCIe bus.

Thank you for that information. So, the 4590 would be the better purchase if I was a hardcore gamer looking to spend $300+ on a PCI-E 3.0 graphics card? But otherwise, the 4460 is the best bang for the buck?

I also hear that they are using PCI-E buses for faster SSDs but I probably won't worry about that for a few years since I just bought my first SSD a few days ago.

I've already ordered the 4460 from NewEgg. Now, I'm retracing all my steps makings sure it was the right purchase for me before it ships.

Edit: What the hell? www.cpu-world.com is showing that the 4590 has a megabyte of L2 cache? That better not be true. I'll cancel my order now.

Intels website show both CPUs having PCI-E 3.0 capabilities and mentions nothing about the presence or absence of L2 cache on either CPU. Wow, so much confusion.

what

both of these are wrong. both have the same amount of cache, both L2 and L3, and both do pci 3.0 (which isn't even needed if you have top end discrete graphics cards)

here's straight from ark:

http://ark.intel.com/products/80817/Intel-Core-i5-4460-Processor-6M-Cache-up-to-3_40-GHz

http://ark.intel.com/products/80815/Intel-Core-i5-4590-Processor-6M-Cache-up-to-3_70-GHz


i can't even imagine how slow a modern CPU would be without L2.

It shows that they are PCI E 3.0 capable but nothing about L2 cache. But I found it somewhere else. NewEgg product descriptions suck. They got me scrambling at the last moment to verify all this stuff. I cancelled the 4460 and re-ordered the 4590. Promo code for a $10.00 discount make them the same price right now.

This page here shows a kick to the balls by Intel if I purchase the 4590:

It appears that the 4590 doesn't have FMA3, EMT64, or F16C instructions. Now, I gotta see if that's accurate and if it matters.

 

[Yuriman]

The only significant difference between the two chips is clockspeed. Both have L2 cache and I'm almost certain both will support PCIe 3.0 as well.

Agreed. After all, you can't have L3 cache without L2 cache that makes no sense!

 

[ShintaiDK]

Direct compare of the 2

[Ratman6161]

If you are doing a build for home (which is what I'm assuming here) the only differences between the two are clock speed and price. For business use, the 45xx also supports V-Pro, SIPP and trusted execution technology (if you are building for home and you have to ask what these are then you don't need them)..

4460 should do just fine. Pocket the extra cash or put it towards a better GPU

The 4590 has all of those instructions. Relax

There was no extra cash to pocket with the promo code. It makes the price of the two processors equal.

So, newegg and cpuboss are publishing incorrect information. Intel isn't publishing "all" information. It's not hard to get confused on all this.

Anyhoo, I cancelled my order. I just may wait for Skylake/CannonLake. I like those names better anyway. Haswell/Broadwell sound like a couple of fags. And if they name their next iteration of the graphics anything close to Iris ... I am gonna snap. "Hey Intel, how about 'Gertrude' for the next generation of your integrated graphics chipset?'. That sounds cool as hell. Yeah.

Inappropriate language for a technical forum, and offensive.

Yeah, it's kind of a PITA with the way Intel segments its processors.

Generally speaking though, higher end chips within the same family have all of the features that lower end chips, do.

Skylake should be worth the wait as long as what you're using now is...usable

It is. I have a dual-core SandyBridge and a dual-core IvyBridge. I've gotten along okay with them for the past few years. I always say I don't need a quad-core but I think I am gonna make SkyLake my first quad-core purchase.

Just bought two Samsung SSD's (850 Evo's). If I install those in each of my computers that will trick me into thinking I upgraded both my computers to quad-core CPUs. Mind over matter, kinda but not.

Sounds like a good plan to me!
