A few weeks back I introduced you all to a tool I’d been working on for a while called Bench.

Bench, in its current form, is a database of CPU performance data allowing you to compare virtually any modern day desktop CPUs. With the recent launch of the Core i7 975 and the Athlon II X2 processors there are now 78 individual CPUs represented in Bench.

In my introductory post I asked what sort of older CPUs you’d like to see included. The top suggestions were as follows:

Intel’s Pentium 4
AMD’s Athlon XP
VIA’s Nano

You asked, and I delivered. Well...I started to at least.

The first chip I added was the Pentium 4 660. Based on Intel’s Prescott core, the 660 was a single-core Pentium 4 with Hyper Threading enabled. In today’s more threaded world, HT is more useful than when the 660 first came out. The chip runs at 3.6GHz and was built on a 90nm process.

In many tests even a Pentium E2160 (1.6GHz dual-core Conroe derivative) is 15 - 50% faster than the Pentium 4 660. The Pentium E5200 kicks the advantage up to the 50 - 80% range thanks to a much higher clock speed than the E2160 (2.50GHz for the E5200). The main take away point is that you don’t have to spend more than $50 - $70 on a CPU to see a significant performance improvement over the Pentium 4 660.

The second chip I added was the Pentium Extreme Edition 955. This was one of the fastest processors ever made in the Pentium 4 era, only bested by the Pentium EE 965. Take two 65nm Cedar Mill die put them on the same package and you’ve got a dual-core Presler. With 376 million transistors the Pentium EE 955 ran at 3.46GHz and thanks to its Hyper Threading support, could execute four threads at the same time.

Intel was right about threading being the future. The quad-threaded Pentium EE 955 fared much better today than I expected, partly due to its ability to juggle more threads. The Pentium E5300 is significantly faster in many areas (40%+ in some tests), but surprisingly there are some situations where the golden oldie is close. Fallout 3 has the Pentium EE 955 within 10% of the E5300, as did the multi-threaded PAR2 test. Overall you’d see a significant performance improvement going to a $70 CPU. Although you may never again spend $1000 on a CPU if you decide to pursue that upgrade.

Lynnfield and then SSDs

In my last Lab Update I talked about working on SSDs, unfortunately I had to leave out the part about me working on a preview of Intel's Lynnfield processor. I must say that the Lynnfield testing went much better than I expected. I had the whole thing wrapped up in under a day and didn't have a single crash or performance issue to try and resolve.

Compared to my early Nehalem testing, Lynnfield actually fared even better. While my first Nehalem ran at higher clock speeds, the first Nehalem motherboards had issues with memory performance. Lynnfield worked very well for what I was testing, although I did hear that CrossFire/SLI weren't working very well on those early platforms.

I am curious to see how Intel manages the LGA-1156 vs. LGA-1366 platform split. Intel claims to be committed to LGA-1366 but I do see a lot of potential in LGA-1156; I believe it'll be a difficult job to maintain both platforms without artificially crippling one. We'll see if Intel is up to the task later this year.

My SSD testing is progressing well. There are a couple of items worth reporting on.

1) Windows 7 does currently support TRIM.
2) No SSDs currently enable TRIM support under Windows 7.

OCZ is expected to have TRIM support on its Vertex drives shortly, potentially within the next month from what I've read on their forums. Samsung's latest drive will have TRIM support once Microsoft has released Windows 7; I'm guessing that means September/October.

Intel is remaining curiously quiet on the TRIM issue. I would like to see the existing X25-M drives retrofitted with TRIM as I think that would be a tremendous goodwill gesture on Intel's part; I get that the X25-M is already the fastest thing on the market, but that's no reason to avoid thanking your customers for their support in my mind.

The WePC Update

Last week I talked about two important trends I'm seeing in the CPU industry. Here's a hint: power management is really becoming more important in microprocessor design.

OCZ's Vertex 30GB and 60GB Drives: Slower?

I've been testing the OCZ Vertex 30GB and 60GB drives fairly thoroughly over the past couple of weeks and I've got some early data to report.

1) The 30GB and 60GB drives are about 20 - 35% slower in sequential read and write speed than the 120GB drives.
2) Small file random read/write speed is unaffected. The entire lineup of Vertex drives, regardless of size, performs the same when dealing with small file random access.
3) As a result, real world performance is mostly unaffected by going for a smaller drive. PCMark scores are only around 4 - 5% lower on the smaller drives.

You should have no issues opting for a smaller Vertex drive, but the 120GB drive continues to be a better buy. Not only do you get better performance, but from what I've seen you get a much lower cost per GB than the smaller drives. OCZ's 30GB Vertex actually has a cost per GB greater than Intel's X25-M.

Expect more of this in my upcoming SSD article.

    i would like to see a northwood p4 in the charts.

    what was the fastest northwood? 3.4 i think?
  • agent_x007 - Thursday, October 3, 2013 - link

    Pentium 4 EE 3,46GHz based on "Gallatin" core (Nothwood with 2MB L3 cache, originally used in Xeon series).
    Ps. Its first chip for LGA775 that uses 1066MHz FSB.

    sorry for the out-of-context post, but this was a blog post so i felt like i should ask it here. well, won't you guys say nothing about the SP2 for Windows Vista? it was released 15 days ago, and the documentations is so vague I am wondering why it is called a "service-pack" anyway. Is there any catch-up on the SP too? SP1 was good enough to get a full article, but SP2 not? does this SP2 brings any "7-like" feature to Vista? tks in advance

    I could not be more happy about the performance of the Pentium-D CPUs. See, I just gave my old computer to my girlfriend and it is a P-D 945 (3.4ghz, 2 cores no HT), and honestly it has more power than she will ever need in the folowing year. and that's because she likes to play some games with high-quality visual (well, not Crysis, but she does not like it aniway!).

    I really believe that the amount of pore-power in today's CPUs is far beyond the ordinary user needs... so welcome Lynnfield! what we need is a cheap platform!

    "...I am curious to see how Intel manages the LGA-1156 vs. LGA-1366 platform split. Intel claims to be committed to LGA-1366 but I do see a lot of potential in LGA-1156; I believe it'll be a difficult job to maintain both platforms without artificially crippling one..."

    I am planning to complete a new build in the September time period. My choice was LGA-1366 with i7-920 but the initial reviews seem to indicate that the Lynnfield 2.80 GHz may hit the price/performance sweet spot in its final released form (I am assuming that LGA-1156 will be able to utilize the DDR3 Triple Channel I have already purchased). The above quote is what raises the big concern for me--which of the 2 platforms is the better bet for survival and future upgrades? Any thoughts?

    I think that many people and offices have Pentium 4 Northwood machines still in operation. Including *just one* Northwood would be helpful. Either the 2.4 or 3.0 GHz model since I think these were the most popular.

    I also think you should incl. a Pentium 3. Why? Because the Atom is essentially the same performance as a pentium 3. But is it? In all cases? Where would it make sense to retire a P3 system (lots of ftp fileservers are quite happy on P3) with an Atom to save power? If we could see performance parity or improvement, then the case for Atom upgrade is made.

    Second comment: I think there are too many CPUs in the database that are identical architecture just at a different speed. All you need is a lower Mhz and a higher Mhz representative of a particular architecture. We dont need every single Mhz step in between going into the database. What for? We can just calculate a weighted average to get approx and accurate performance stats for the other models.

    I think you have a great tool in Bench. I also think there is lots of opportunity to expand it and make it even better and more useful. Adding prices and the ability for users to add their own prices and do a performance for money comparison using either would be great. It would be nice to see the Benches for each processor OCed. This could just be on air, and give an approximation of OC headroom/performance, and also allow users to do a performance for money evaluation.

    With the introduction of more processor features like on chip virtualization, and other differentiators, it gets more difficult to compare and do analysis on what's out there. I hope this tool can continue to be expanded to evaluate different areas of processor features and performance.

    PLEASE include the new ioXtreme PCI-E SSD in your next update! I am sure Fusion-io would love to give a review model if what they say is true in their marketing. This drive may have just owned every SSD on the market!

  • shabby - Tuesday, June 9, 2009 - link

    I don't think its bootable, making it somewhat useless for an os drive.
  • Norseman4 - Tuesday, June 9, 2009 - link

    I read on DailyTech that JMicron has (or will shortly have) a new SSD controller with TRIM. Was wondering if you had anything to test for that.

    (Even if it's to say that they missed the mark again)
