The Lynnfield Preview: Rumblings of Revenge

3dsmax 9 - SPECapc 3dsmax CPU Rendering Test
Today's desktop processors are more than fast enough to do professional level 3D rendering at home. To look at performance under 3dsmax we ran the SPECapc 3dsmax 8 benchmark (only the CPU rendering tests) under 3dsmax 9 SP1. The results reported are the rendering composite scores:
There are three key takeaway points here.
1) Hyper Threading allows the i7-920 to outperform the entry level Lynnfield by nearly 18%.
2) With HT disabled, the $196 Lynnfield is faster than the $316 Core 2 Quad Q9650. It's a true replacement for Penryn in the lineup.
3) Intel could release an even slower Lynnfield and, by enabling HT, offer a chip faster than all other Penryn and Phenom II based processors in the market.
Cinebench R10
Created by the Cinema 4D folks we have Cinebench, a popular 3D rendering benchmark that gives us both single and multi-threaded 3D rendering results.
The single threaded Cinebench test shows us just how powerful the Nehalem core is. Remember, we're looking at single-core performance here.
Without an aggressive turbo mode, the 2.66GHz Lynnfield sample is faster than a 3.0GHz Penryn. Even at 2.13GHz Lynnfield is able to perform like a 2.5GHz Penryn. This is a very flexible core.
These results also give you an indication of exactly how strong the dual-core Nehalem derivatives will be in notebooks late this year and into 2010.
Crank up the thread count and feel the frustration brew. The entry level Lynnfield won't have Hyper Threading enabled, and thus it'll only outperform the Phenom II 955 by 3.4%. Had Intel enabled the HT switch, Lynnfield would not only be 16% faster than AMD's best but it would also be only 5% slower than the i7-920.
POV-Ray 3.73 beta 23 Ray Tracing Performance
POV-Ray is a popular, open-source raytracing application that also doubles as a great tool to measure CPU floating point performance.
I ran the SMP benchmark in beta 23 of POV-Ray 3.73. The numbers reported are the final score in pixels per second.
We see a similar story in POV-Ray.

P55 essentially has the same ICH feature set as P45. You get support for six SATA 3.0Gb/s ports, 12 USB 2.0 and PCIe 2.0.Intel's chipsets are actually what I use for all of my SSD tests and they work quite well. I wouldn't expect any different out of P55.
Remember that P55 is only the first Lynnfield chipsets, next year we'll see more. This chart speculates on some of the features of those (it also lists 14 USB instead of 12, I'm not sure which one is right):

I thought so...I hope someone will adopt the changes quickly.
It's about time to get rid of the BIOS and make room for speed improvements int the Flash chips (Both via the SATA 3 and USB 3).
Do you see in the horizon how long will it take before will see those features?
Thank you for the response.

I find it very funny when people make a huge fuss over a 2-10% difference in performance (i5 versus i7). It is sad that even budget CPUs are bloody overkill for majority of computer users.The bottom line is that i5 is going to be Intel's next big winner. It is the perfect Phenom II killer and an excellent successor to the Core 2 parts that it is replacing. I7 makes very little sense unless time is $$$$$.

Exactly. My nearly four-year old S939 Athlon 64 X2 still performs everything I do (with one exception) more than fast enough so the difference between the i5 and i7 would be irrelevant. I still think I'm at least a year or two from doing a new build (the only thing of any value at all in my current box I could reuse would be the graphics-card, a 640MB 8800GTS; most of the drives are parallel ATA, and the memory is of course DDR).Given that the one app where my current rig struggles is PCSX2 (a Playstation 2 emulator), it seems kind of silly to spend upwards of £500 for a new box simply to play PS2 console games, when I could probably buy a new PS2 console for under £100. Therefore debates over the relative merits of i5 and i7 which are both much faster are rather moot for me at the moment, and the vast majority of the PC buying public. It is nice to know how they compare though, and what their pros and cons are (the main con I see being the price of X58 mobos), so I'm thankful for this informative article on AT.

I don't quite understand why X58 boards are so expensive. At first we were complaining about ddr3 prices.. but they've come down to a managable point. While cheaper X58 solutions are starting to crop up it's still extremely high and I don't quite get why that is.With the memory controller integrated into the chip you'd think that the cost of the boards would be cheaper overall. That was one of Amd's main selling points (if I remember right) but for the i7 not the case.. the boards are priced incredibly high.
Anand Lal Shimpi - Saturday, May 30, 2009 - link
It's artificial. The boards are priced so high because Intel charges quite a bit of money for the X58 chipset. It's the cost of competition; if AMD had a true answer to i7 we'd have much more affordable i7 platforms all of the sudden :)Take care,

Chipset and processor prices are two different things. Neither are related to each other. Like all products, prices of chipsets is related to other chipsets competing at the same level. Since the X58 does not have any competitor, people have to pay a high premium for a complete i7 system. If nVidia is allowed to make a chipset for the i7 processor, we will see these high premium prices decrease. Since the i7 processor is designated as enthusiast setup, prices will still be at enthusiast pricing.just4U - Saturday, May 30, 2009 - link
You've had them on your test beds so you'd know better then I. Hell I haven't even gotten any hands on with the i7 since people here keep opting for the PII. Not that that's a bad thing, I am rather impressed with those overall just..Im beginning to realize the only way Im going to get my grubby little paws on a I7 is if I go out and build it for myself. Even I balk a little bit at the price tag of some of those boards but there are a few coming down the pipeline that look a little bit more reasonably priced.

EX58-UD3R = $150 from eWiz ;)goinginstyle - Saturday, May 30, 2009 - link
It is $185.99 at eWiz with a $15 rebate that will take two months to get for an end price of $170.99.
