'Nehalem' 2.93 GHz Benches Revealed

By - Source: Tom's Hardware | B 3 comments

Several days ago we took a look at Intel’s next generation X58 platform for Nehalem in which we explained that the new chipset will be bringing along several new features. The most significant of these features is QuickPath, which is a brand new link architecture very similar to AMD’s HyperTransport, and getting rid of the front-side bus (FSB) system altogether.

What will happen is that the connection between the CPU and the northbridge (X58 MCH), will be based on an external clock multiplier running at 133 MHz. At this time, with an early X58 sample motherboard on hand, we’re still unable to change this frequency, but our motherboard sources tell us that this is a feature that will be available via the system BIOS once things go into full production.

Intel Nehalem (CPU-z)Today however, we were able to really play around with a 2.93 GHz quad-core ’Nehalem’ processor. Unfortunately, we were not able to test the system for long, and therefore very little comparison could be made to another system. However, we did manage to run the chip through some common synthetic benchmarks. We will definitely be providing a full performance review. For today though, we have a quick look at how Intel’s next generation platform performs.

We used the following system specifications :

ProcessorIntel Nehalem 2.93 GHz
MotherboardPrototype X58 motherboard
MemoryCrucial Ballistix DDR3-1600 1GBx2
StorageSeagate SATAII 750GB (ST3750330AS/P)
GraphicsATI Radeon 4850 HD
OSMicrosoft Windows Vista SP1
Resolution1280 x 1024
Patcheshotfix_vista32-64_dd_ccc_hd4800series_64906

The results so far are :
3DMark 06 1280x1024 noAA
3DMarks12786
SM2.0 score4605
HDR/SM3.0 score5600
CPU score5183

PCMark 05
PCMark9852
CPU score9583
Memory9010

Just for reference, a similarly configured Core 2 Extreme X6800 at 2.93 GHz delivers a CPU score of 7417 — roughly a 23 percent difference clock for clock, core for core. When compared to a similarly equipped AMD Athlon FX-62 system, the gap widened even more, to a staggering 31 percent difference, with ’Nehalem’ taking a long distance lead. Keep in mind t hat this is actually very impressive, because our Nehalem platform is running on very early hardware, specifically the motherboard. We are expecting even better margins in the coming months as the platform matures.

CPU Test1 (Plans/S)2515.1
CPU Test2 (Steps/S)23.08

Although this is a short preview, it gives us an overall idea of the potential that’s in Intel’s next-generation CPU. Nehalem is a huge step forward for Intel in many ways, leaving behind some old concepts, and taking a big step forward in other areas.

At its expected announcement in Q4’08, Nehalem will be released initially with 4-cores, and later scaling up from there. One detail to note is that HyperThreading makes a nice comeback as well. Our CPU read as 8 processors in Windows Vista.

Frequency potential with Nehalem in its current state of silicon, is very healthy, Intel told us during Computex earlier in June. With our preliminary tests of the 2.93 GHz CPU, we’re confident in saying that enthusiasts can expect even faster processor frequencies down the line.

Keep in mind this article is not meant to be a review, but is a short expose on the potential of the Nehalem family. We hope it gives you an idea of what to expect.

    Hyperthreaded octo-core running at 4GHz on air cooling? I think I just leaked a little...

    Question. WHY ?
    Answer. Just because :) 
    Seriously though this will be great for encoding etc but its going to take a while until we actually need a 4GHZ Octo watsama supa thingy for day to day use. Isnt it?
    Then again Vista needs all the help it can get. Do you recon one of these will be entry level for windows 7 :)

    To be honest, for my video production and motion graphics work I'd LOVE to have an octo mother like that - even if my software doesn't take advantage of all 8 cores I can at least run different packages at the same time.

    Will just make my life easier!
