OpenGL Gaming Performance

The performance of Northwood Celerons is horrible here, but Prescott takes the lead in Quake III.

Wolfenstein: Enemy Territory is based on an extended version of the Quake III engine, and under this benchmark, the Athlons come out on top.

    Can we get a comparison of a P4 2.4A (Prescott, 1MB L2 cache, 533 MHz FSB) compared to these new Celeron D processors? Reply

    Yeah, there's something more to this than meets the eye. I dont really follow your cache arguments, Derek (and I'm known not to like caches when they are irrelevant). To me what applied to the P4E applies to the celeron D. Its a pity you didnt throw in a 533MHz 2.8E in your benchmarks. I predicted the Prescott celeron would be a good buy but more on the basis of less heat and better o'clocking. The only conclusion I can come of all this, is the Prescott core is better than we think but the cache structure is the problem. Else they've changed something in the pipeline architecture of these celeron Ds which may have ramifications for later stepping P4Es.

    #39 - Oh. Dang. Oops. Still, I think I probably would have chuckled more than anything. Who here hasn't made a major mistake at some point in their life? The only problem is that with Internet "publishing", your mistake can be put on the web in minutes rather than days.

    Wonder how many "Flame AnandTech" threads have started up on other hardware forums about the original article?

    Just out of curiosity, what's the actual transistor count and die size of the Celeron D?

    With the trimmed down L2 cache, that cuts out about 40 million transistors. If they removed dormant 64-bit stuff from the Prescott core as well (or some other unnecessary additions), we're down to almost the same transistor count as Northwood, except with a 90 nm process.

    Even with 75 million transistors, if it still uses 8 layers like Prescott (and not 6 like Northwood), that would put the die size at less than 70 mm2 by my calculations. Yowza!

    Picture this: 70 mm2 die size CPUs on 300 mm wafers. That gives an absolute maximum of 1009 CPUs per wafer, minus those that are on the outer edge (i.e. partial cores). Even with conservative yields of 60%, we're talking about roughly 600 CPUs per wafer. No wonder they're so cheap.

    Unfortunately, TrogdorJW, most of the premise of the original publishing was based around the assumption that the Celeron D was able to out perform its predecessor inspite of having an equal sized cache.

    It was a very large error, and certainly worthy of the outrage people have voiced.

    Thanks for sticking up for us though. And please be assured that we will be much more careful. Again, we appologize for the error.

    I think some overclocking results are definitely in order, though. Take the Celeron D 325 2.53 GHz part and overclock that to a 166 MHz bus and you get a 3.2 GHz (3.167 GHz) part. It would be interesting to see how that compares to the P4 3.2C and 3.2E - Sure, it will still be (a bit?) slower, but at less than half the cost!

    I'm guessing that a 200 MHz bus is unreachable, as that would give you 3.8 GHz. Then again, from the 915/925 roundup, it seems that 3.8 or 3.9 GHz was reached with many of the Prescott CPUs. Damn... $80 for a CPU that might actually get close to 3.8 GHz!? Either I'm dreaming - entirely possible - or we have a return of the good old 300A overclocking days! Pray for the latter!

    So, seriously, let's have the overclocking results, and compare that to regular P4, Athlon XP, and Athlon 64 results.

    Mino, considering that you can't even write a single sentence without spelling and/or grammar errors, I would think that calling the article "full of errors" is rather like the pot calling the kettle black. "I didn't intend to make me looka 'smart', nor is my opinion I am." Way to make yourself look even dumber! Granted, I'm looking at the corrected version of the article, but even if I had read it with the incorrect L2 cache size, it's not that big of a deal. (Unless the original article had statements along the lines of, "even with the same size cache the new Celeron D outperforms... blah blah blah..."?) Reply

    #32 actually U are WRONG, fastest BUDGET proc from AMD is AthlonXP 2800+ which compared to Celeron2.8(here in SK called "Zelenina"-> means "vegetable") is like horse to ponny;)

    However Cel. D is welcome improvement from Cel. based on Willys and Northwds. It is however move from near unusability(but like heater they were gut:) to low usability. Improved computing and heating performance is a good sign, especially ina winret nights when tey turn off heating ussually in my work :).

    intel must be making these things cheap, 90nm process and only 256kb l2

    also the number of celerons sold in cheap emachines and dells is high right?

    #31 Eh, sorry, by "Anand" i meant shortened word "AnandTech".

    My mistake, won't repeat:-).
