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.

Photoshop performance is actually very good on these chips, the extra cores help make them faster than even a Phenom II X3 720. For $99 you're getting better Photoshop performance than even more expensive dual core processors.

The Pentium E6300 isn't competitive here, despite being Intel's closest priced processor. The Q8200 is faster than both of these options, but it's also more expensive. Again, AMD priced the 620 on point.

    Sure, AMD has been forced to realise that competing at the higher end is a worthless exercise thanks to Lynnfield, however they've had Propus on their roadmap for a year now so I'd hardly term it "Emergency Edition". It's not a clock-speed bump like a certain Emergency Edition we all remember (how much did the various P4 EEs cost again?).

    With AMD providing a more complete platform, and especially one that allows for easy upgrades, the new Athlon II X4s could work for them in that it'll be cheap to upgrade from the old Athlon X2s as well as relatively inexpensive to build a new setup with CPU/motherboard/RAM (remember the onboard Radeon still runs rings around any Intel IGP). I doubt that i5/i7 sales make up most of their current order book (hell, they're still advertising Core2 on television and in IT publications here in the UK) so, like with graphics cards, the majority of the money stands to be made from mainstream and value products. As someone said before, this could be great for OEMs to improve their margins, as well as AMD if it means more bundles are sold. What's more, as things get more multi-threaded, dual cores fall more and more below the curve.

    I'm interested in seeing what Intel does, and even though their market share has grown again this quarter, I don't believe they can just do nothing about the Athlon II X4. Generally, below $150 or so, AMD does offer better performance for the price, even if, per clock, an Intel chip does more (and it's not always down to Intel-specific optimisations either) and earns its maker more money.

    Slight clarification on the P4 EE; it wasn't just a clock speed bump (3.2GHz -> 3.46GHz -> 3.73GHz) as, for example, the FSB was increased with the 3.46GHz model to 1066MT/s, then the core changed from Gallatin to Prescott (inc. extra cache) for the 3.73GHz model.

    Don't want anyone to think I just picked on the P4 EE just because it was fashionable or anything :)

    Microcenter is advertising a special on the i5 750 at $159. But even at the full $206 suggested retail, if you are really doing something that benefits from 4 cores, it doesn't really make sense to me to go with anything less. There are even 1166 motherboards for just over $100 so the $99 quad just isn't saving enough to make it worthwhile. Reply

    On page 6 of the review the Excel Monte Carlo Simulation test shows the Q8200 (2.33GHz) being faster than the Q8400 (2.66Ghz)

    Same thing happens again on page 7 on the WinRAR Archive Creation test.

    You didn't mention it in the text and it's very unlike you to overlook or fail to comment on such an odd result.

    you said
    Overclocking suffers a bit as the chips capable of the highest clocks are destined to be Phenom IIs.

    And I think this does not make any sense. These are probably manufactured on their own wafers, and they are not Deneb dice, but completely different dice, so regardless of the clockspeed that any individual die is capable of, it cannot become a Phenom 2.

    You're quite right :) I clarified in the article. That would apply to rebadged Denebs, but as to why the Propus core doesn't clock so well it's not totally clear to me at this point.

    It could be a design decision or just the impact of manufacturing a brand new die or just a bad sample.

    Note that I could get the chip a lot higher but it wasn't stable by my definition :)

    Take care,

    It's not overclocking. These chips are rated to run at "turbo" speed indefinitely. Each of the 4 cores is capable of running at that speed. However, for power and thermal management of all 4 cores, the on chip power management "underclocks" the cores dynamically depending upon load to keep the combination of all active cores from exceeding thermal and power limits.

    Intel is being very honest in listing the speed as the slowest speed at which all 4 cores can run concurrently, even though they're all rated to run 1.5x bus multiplier steps faster. The difference between the slowest "underclock" and "turbo" mode on the upcoming Core i7 mobile chips is reported to be much more than 1.5x (~6x). Again, that's for power (mostly) and thermal management, allowing it to operate as a fast single/dual-core or slower tri/quad core depending upon current usage.

    The reality is that most software can't currently take advantage of more than 1 or 2 cores, and for those applications, you're going to get the benefits of turbo mode. When you're running tasks that can benefit from 3 or 4 cores, the cores reduce their clock to limit the power and heat, giving lower performance on each thread, but higher total throughput.

    The user gets the benefits of a fast dual core and a slower quad core, depending upon current load. Because all of that power management is handled by the PM on the CPU, it's transparent to the OS.

    I see many angry users concern about the term overclocking. It strikes me hilarious that people really claim to know what Intel is and/or have actually done with their chip.

    I too agree it is not a fair comparison because the Turbo mode does increases the frequency. Granted that this is a feature of the chip itself but that is a feature that is not present on the AMD and hence isn't a apples to apples comparison. If you're going to represent Intel with a 600MHGhz boost why not compare it to a regular clocked AMD and an AMD chip that is clocked around the same turbo-boosted speed. That would be a fair comparison and would give anyone a clearer picture.

    The reason why the arguments by most of the users here are hilarious to me is that I don't think they have a clue to how the CPU's were tested. We have had CPU's that were generally locked to keep the speed/price ration. This "feature" was not presented as a feature to the consumer but once the market found out the chip could actually provide more then they in a sense enabled it. So the difference here now is is that Intel is making this available, unlocked and calling it a feature and suddenly cries of joy and stupidity are abound. Yes, yes, the technology isn't entirely the same but the end result is.

    Do you seriously think Intel did not overstress test their chips and fool-heartily tested only at stock. Do you think they didn't test them in turbo mode and still continue until the chip died? I can't recount the 30 years on my engineering career not having to test products in the extreme range of just about anything (temp, vibration, shock, emc, drop, shipping, customer use, etc.). If you are an engineer and don't do this you shouldn't be selling your shtty product, end of conversation. Feel free to disagree and be laugh at by the industry.

    Having said of of this the simple matter is that if Intel's feature is boosting the clock by 600, then why not compare an AMD chip with similarly clocked speed? And further more, why do you even rant about having to do this in the first place? Getting caught up in this "overclocking" terminology and not looking beyond what stands to reason is ignorant. At the very least I would hope to see the lower price Intel I5/I7 compare with the competition in default and turbo modes. Why wouldn't YOU?

    Flame away,

    Weather its overclocking or not, leaving the turbo feature on the i5 makes it a good comparison for those people who want to just plug in the chip and run it within its specs. You are comparing "out of the box" speed of one versus the other. It doesn't make sense for every one, but I think the article gave enough information for the knowledgeable reader to make their own decisions. Reply

    How can anyone advocate intentionally crippling the superior product in order to make the comparison more favorable for the competition? That's like a car magazine intetionally removing the turbo from a factory turbo charged vehicle so "that would be a fair comparison and would give anyone a clearer picture."
