Core i7 860 vs Core i5 661
#1
Hi guys,

I've been saving money for the past 6 months to buy a new rig.

Processor: Core i7 860 or Core i7 661
Motherboard: Gigabyte GA-H55M-USB3 [Cheapest 1156 Gigabyte Mobo with Ultra Durable 3 Feature]
Casing: Cooler Master HAF 932 (RC-932) Gamer's Case [Biggest and cheapest as much as possible]
HDD: WDC Caviar Black 640gb/32mb (WD640AALS) dual processor sata [They say black has solid performance]
PSU: Corsair TX750 750watts
RAM: 4gb (dual) ddr3-1333 G.Skill RipJaws (F3-10666CL7D-4GBRH) CL7 (7-7-21) 1.5v [Same price with CL9 ddr3-1666 but most people said that CL7 1333 is faster, Not to mention I want to make sure it's 1.5v]
VGA: Sapphire HD 5770 1gb/128bit ddr5 Vapor X [To be replaced with Sapphire 5870 Vapor X after a year]

I'm definitely going for a 1156 Board since I don't have any plans to do SLI/XFire and overclock as well.

I'm quite sure the 860 will outperform the 661 in terms of playing the latest PC games out there, but as for PCSX2 I'm not quite sure.

I came across with a topic here [I forgot the link] comparing CPUs using a scene in Final Fantasy. The results show that 661 has 57 fps while the 920 is lesser than that. [Assuming 920 ~ 860]

So the main question is: How much fps will I lose if I'll go with the Core i7 860? FYI: I'll not overclock my processor and I'll be playing the FF series, GOW, MGS3 and Tekken 5.

Thanks a bunch. I'll be posting benchmarks once I have the rig. [Excited] Laugh

You can just overclock the CPU.

in pcsx2 the i5 will be faster but in everything else way allot slower:

I'm actually thinking the i7-860 might come out ahead. Assuming Turbo Boost was disabled in both benchmarks, then the i7-920 is faster clock for clock. The i7-860 can Turbo up to 3.33GHz (dual-core) or 3.46GHz (single-core). If it can hit 3.33GHz while running PCSX2, then it'll perform just the same as or even better than the i5-661.

By the way, the Final Fantasy X-2 FMVs are somewhat unusual. You'd actually get higher framerates during actual gameplay.

I actually have a Core i7-860 (MicroCenter, $200) on-hand. Just didn't have a motherboard I can test it on before but now I do so perhaps I can play around with it tomorrow.

Yeah Turbo Boost is quite interesting. I hope you can share the results once you're done. Smile

@iakoboss
More like PCSX2 vs Recent PC Games. Bah, I love them both! Glare

@sakraycore
Your suggestion would be better for others since I really don't want to overclock. Although the turbo boost feature might come in handy, but I'm not sure how will it affect PCSX2.

the i7 860 is a better processor however I will say if your just looking to be on PCSX2 and moderate gaming the i5 will do just as good as games really only utilize 2 cores and pcsx2 shouldn't see a speed increase if any would be small.

Just thinking of the price difference since the 860 costs more than the 920/930.

If you would be willing to overclock the i3 would be as good a choice as well and that runs really cool and so easy to overclock its unreal. Just get a CPU Cooler and throw that to 4ghz.

Also don't forget that the 1156/1366 socket platform dies in early 2011 to pave way for the universal 1155 socket platform. Better to go the cheapest way possible i.e i3 with overclock.

nah 1155 will just use the larrabee technology for intel graphics that will have the cpu and gpu in 1 die (or something like that) nothing to do with the 1156-1366 sockets.

Results are out:
57.87 FPS - SLUS 20672 - Intel Core i7 860 - 2.80 GHz Stock (Turbo Boost on) - ilovejedd
51.95 FPS - SLUS 20672 - Intel Core i7 860 - 2.80 GHz Stock (Turbo Boost off) - ilovejedd

A comment, while the 57.87 FPS on Turbo looks nice, it's not consistent. On the exact same frame, the lowest reading I got was 54.33 and the highest 57.87. Median is around 56 FPS. That's pretty darn good performance at stock.

Dunno why you say the i7-860 is more expensive than Bloomfield. A quick check on Newegg shows it costs the same as a Core i7-920. I actually got mine from MicroCenter for $200. For that price, it's a no-brainer. Laugh

Even so, the Core i7-860 is still pretty formidable and I reckon would not need upgrading for a while.

Aside from superseding both sockets, Sandy Bridge probably means no more upgrades for LGA-1366 and LGA-1156.

@eril0809
The Core i5-661 would give you more consistent frame rates but the results you'll get from Lynnfield won't be far behind and Lynnfield would work much better in other programs. Assuming you're paying normal prices, I personally wouldn't consider the Core i5-661. It costs the same as a Core i5-750 and Turbo Boost pretty much eliminates most of the i5-661's clockspeed advantage.

Intel Core i5-750 vs Intel Core i5-661

By the way, how against overclocking are you? I think the higher multipliers used in Turbo Boost might be available in the BIOS of some motherboards. Assuming they're available, you can set the BIOS to use the higher multi, sort of like putting it permanently on Turbo. That way, you'll get more consistent performance out of the i7-860. Turbo Boost is just Intel's version of automatic, on-demand overclocking, anyway. Laugh

the i3 530 with a standard little overclock to 3.3ghz scored the same as your i7 860 turbo boosted to 3.3ghz (well within the margin of less than 1fps)

57.04 FPS - SLUS 20672 - Intel Core i3 530 - 3.3 GHz OC - ilovejedd
I would imagine that was stable so proves the point I was making pcsx2 sees no improvement over it and the i5 would do better at stock since it has a base clock of 3.33ghz and can then be turbo boosted to see a better fps over both.

However overclocking will see the i5 probably no better than the i3. However the i3 and i5 will beat the 860 as they both have amazing overclocking potential over the 860 as there dual cores and have a higher limit.

the i7 860 has 8 thread right? y the hell wouldn't you get it (forgive me but I didn't read this thread yet so if you already answered this, answer again because I said so Tongue).
