SYSMark 2007 Performance

Our journey starts with SYSMark 2007, the only all-encompassing performance suite in our review today. The idea here is simple: one benchmark to indicate the overall performance of your machine.

SYSMark 2007 - Overall

Ok. Right out of the gate, on pre-production silicon, with a pre-production motherboard and without a super aggressive turbo-mode the 2.66GHz Lynnfield sample is able to perform just as well as the i7-920. This is just as we expected given the minimal impact of triple-channel DDR3 on i7 that we pointed out in our original review.

Curiously enough, HT doesn't seem to do anything at all for Lynnfield in this test. Remember that stressing four cores is tough enough, finding eight CPU intensive threads is even more difficult.

Adobe Photoshop CS4 Performance

To measure performance under Photoshop CS4 we turn to the Retouch Artists’ Speed Test. The test does basic photo editing; there are a couple of color space conversions, many layer creations, color curve adjustment, image and canvas size adjustment, unsharp mask, and finally a gaussian blur performed on the entire image.

The whole process is timed and thanks to the use of Intel's X25-M SSD as our test bed hard drive, performance is far more predictable than back when we used to test on mechanical disks.

Time is reported in seconds and the lower numbers mean better performance. The test is multithreaded and can hit all four cores in a quad-core machine.

DivX 8.5.3 with Xmpeg 5.0.3

Our DivX test is the same DivX / XMpeg 5.03 test we've run for the past few years now, the 1080p source file is encoded using the unconstrained DivX profile, quality/performance is set balanced at 5 and enhanced multithreading is enabled:

DivX 6.8.5 w/ Xmpeg 5.0.3 - MPEG-2 to DivX Transcode

Once more, we see very little impact from Hyper Threading; the entry level Lynnfield may not be as bad as you'd think. On top of that, the crippled Lynnfield is less than 4% slower than the Core i7-920. Enable its aggressive turbo mode and I believe we'll have a chip that can actually beat, even if only slightly, the Core i7-920.

x264 HD Video Encoding Performance

Graysky's x264 HD test uses the publicly available x264 codec (open source alternative to H.264) to encode a 4Mbps 720p MPEG-2 source. The focus here is on quality rather than speed, thus the benchmark uses a 2-pass encode and reports the average frame rate in each pass.

x264 HD Encode Benchmark - 720p MPEG-2 to x264 Transcode

The x264 encode test shows one application where Hyper Threading is important. A 2.13GHz Lynnfield with HT enabled is faster than a 2.66GHz Lynnfield with HT disabled, unfortunately the former isn't on the roadmap and the latter is what we're getting.

Without HT enabled the $196 Lynnfield 2.66GHz core is faster than every non-EE Penryn Core 2 Quad as well as AMD's Phenom II X4 955 (in the second pass of the test). The i7-920 is significantly faster thanks to having HT enabled; and now we have the perfect reason for Intel disabling HT on the "low end" Lynnfield.

Windows Media Encoder 9 x64 Advanced Profile

In order to be codec agnostic we've got a Windows Media Encoder benchmark looking at the same sort of thing we've been doing in the DivX and x264 tests, but using WME instead.

Windows Media Encoder 9 x64 - Advanced Profile Transcode

Tests that don't scale well with HT enabled, once again, show no performance difference between a 2.66GHz Lynnfield and a 2.66GHz Bloomfield.

    Man thats ancient ... ya I would defiantly wait for the Core i5s. To get a Core i7 just doesn't seem worth it now with the Core i5's coming out. Reply

    i7 still makes sense if you plan on

    a) SLI/CF

    b) dual-CPU

    c) memory bandwidth intensive tasks (seeding torrents, folding@home, etc) where triple channel makes some sense

    d) the need for 6 memory slots

    e) something currently purchasable

    I also suspect the release of "i5" chips will drive down prices of i7, specifically the i7-920, the most desirable i7. Keeping in mind the i7-920's overclocking ability, it is still much more capable than the "i5" even if you assume the "i5" overclocks as well, because the i7 has Jackson technology active across its entire lineup.

    I swear I read that the i7 doesn't support dual CPUs. Maybe that has changed with xeons though or I might just be insane. Probably the latter. Reply

    i7 system is too expensive, cpu is also expensive but system is too overpriced. Reply

    ^ This, although for me personally (b) isn't important and I've effectively nerfed (d) by using an EX58-UD3R :P Reply
