Which CPU Is Tops in Price/Performance? 345

Posted by Zonk from the zing-for-your-buck dept.
mikemuch writes "You can spend 150 bucks or over a thousand on a processor, but how do you know which gives you the most power for your money? It's a little like MPG for CPUs. ExtremeTech's Loyd Case does extensive benchmarking on twenty-three current desktop processor flavors from AMD and Intel. While of course most folks won't make dollar-efficiency the sole basis for their chip decisions, it's interesting to see which CPUs get you, for example, the most frames per second in Far Cry for a dollar." From the article: "Take PC games, for example. The cheapest CPU available may have the best frame rate per dollar ratio. But you still need an adequate frame rate for an optimum gaming experience, and the cheapest CPU may not deliver that. On the other hand, office applications are generally not as sensitive to raw performance, and the lower cost processor may be better. It's all in what you do."

      Given away by whom?

      I recently got an old server from my office for free. It was dual capable, so I figured I'd stick another PII 450 in there for fun. What could it cost, like $10?

      Called up Dell to make sure that it could handle the 450, and I was offered to buy it from them. Get ready for the price:

      $457.

      That doesn't include installation or anything. I literally laughed out loud and the guy on the other end said "Yeah, you should probably get it somewhere else."

        That's not uncommon. When a company doesn't want to carry/sell a product, instead of saying no, they just price themselves out of the market. That way: a) The customer never hears a, "no", which is something to avoid. b) If someone actually does buy from you at that price, what the hell, you made a buttload.
        I ran into this on my home printer. I bought an HP 2550 printer (for doing all of the printing for my wedding). It comes standard with 64MB of RAM. This is plenty until you start sending graphics to the printer. So to stop the "Out of Memory" errors, I decided to upgrade the memory. The printer would handle an extra 128MB SODIMM.
        Price from HP: US$800 [hp.com]

        And, it only took me moments to find the right part with Kingston's website (they have a really nice memory finder). Also, Kingston offers a lifetime warranty and puts out a solid product, so no worries about a fly by night company.
        So, in the end, I got what I wanted and HP got to stay out of the memory business, without ever explicitly telling me "no".

        i think the reason most companies do this is because they expect most the people looking for a PII 450 to be some unlucky sap who still has that running as their server at work and they know no better then to pay Dell $457 for a new CPU because they HAVE to keep the server up. Sometimes it is said how dense some IT departments and their managers are when it comes to parts...

      I'd say that a processor produces ZERO mechanical work.

        The real sweet spot here looks to be the Athlon 64 3800+. While lower-cost processors will give you a better frame rate-per-dollar ratio, some of the games tend to get a bit chunky in some titles--Splinter Cell: Chaos Theory, for example.

          What you commonly see as an "800MHz" FSB speed for an Intel system is, in fact, a 200MHz bus that can transfer 4 times a second, and you get 800 Mega-Transfers per second (MT/s). The Intel bus is 64-bits wide, so that is 6.4GB/s of data transfer.

          The AMD interconnect is 1000MHz HyperTransport. This is the correct clock speed, but HyperTransport is DDR, meaning it transfers twice a second. Therefore the AMD bus transfers at 2000MT/s. However the AMD interconnect is 16-bits i

    I like how after the full analysis, the ultimate result is that there's really no answer. Cheap is slower, expensive is faster. Dual core has poor support in Windows currently.

    Not exactly surprising, but I wonder how much of that is tied to the OS (f'rinstance, dual core kicks ass on OS X for processor-intensive tasks). Similarly, I wonder how much of it is simply benchmarking the wrong kinds of things. Comparing "office productivity" is mostly useless, as they say in the article, yet it still gets benched. Similarly, graphics, while still relying on the CPU, uses the GPU more and more.

    I've found in my own little "tests" that heavy-duty rendering and long-term CPU processes are really where the benchmark tests are at. Fire up something like VirtualDub and compare the time it takes to transcode video files, for instance, or use ffmpegX on Mac OS X. That's where the real CPU tests come into play. Not office and games.

    (I'd also be curious to see what happens if you start switching around operating systems. Test to see if an AMD chip and NVIDIA board is better running a Linux flavor compared to Intel, for instance).

    I haven't been deep in numbers for processor performance over the last couple of years. I've found the processing speed to be so fast lately that the software I use or care about runs FAST on most modern processors.

    That said, when someone asks me for advice, unless they have some specific high-end gaming requirement, the only advice I offer is don't buy a Celeron!

    Other than the poor performing Celeron I suspect most processing bottlenecks today are more from insufficient memory, bad or slow bus architectures, network latencies, and disk I/O bandwidth.

    Frustrating to me is the non-sequitur naming of technology, I don't know if it's done intentionally to confuse the buying public. A friend of mine saw the ads for some manufacturer's laptop with Centrino technology (which really isn't about processor anyway), and went to her favorite electronics store and got talked into a laptop with the Celeron (mistakenly remembering the "C" word incorrectly).

    I haven't bought a new CPU for years. In the past I would look at the fastest CPU on the market, and then buy one that runs at about half the speed. It helps to also buy a motherboard that supports faster CPUs.

    For example, I bought a new system back in 2000. I think the top of the range Intel chips then were P3s @ 700-800 MHz. I bought two P2-450s for my computer. A few years later I bought two P3-850s, which was the max the motherboard would take. For those four CPUs, I paid less than the price of a single P3-550 back when I was originally shopping around.

    Buying top-of-the-range CPUs is just a waste of money. Gamers are the biggest fools of the bunch with their obsession to have the latest and greatest.

    I work in a high performance computing center, and we just recently acquired a new cluster. One of the major items that we looked at was the amount of heat that is generated by the systems, as cooling systems for large amounts of equipment can be quite costly. We went with AMD dual core systems because we were able to load up with twice the number of systems and cores (thus a 4X overall improvement in number of processors) for a heat load that was actually less than the old system we had that was running Intel Xeon processors.

    Shifting to a DC powergrid helped a lot too.
  • Aside from the HPC circles, I've never really seen a price/performance analysis like this before. I was even more surprised at the results. The P4 3.06 GHz processor came out in November of 2002, the Athlon 3000+ came out in February of 2003 and the P4 3.0 GHz with the 800MHz FSB came out in April of 2003. And these were the winners in terms of price performance with not much more raw performance in the newer and much more expensive chips.

    So, what does this say? To me, it says that SMP and mulitcore is

    Given that most CPUs are overkill for non hard core gamers or encoders. Anyone can be more than happy with a AMD XP 3000. And right now those are going for pretty cheap, I think Tigerdirect was running a combo sale 3K and mobo for $100. And when you notice that it is slim picking to find a app that needs more than 1.8Ghz, I would say you are doing pretty well there.

    Sure you can solve little man's syndrome by buying an "efficient" powerhouse Processor, but what good is it when you wont see any difference 99% of the time and you can save $400.

  • As far as I can see the only thing being included in the price side is the price of the processor. However to get something that is of any use, say in a rendering farm, you need to add motherboard, memory, disk, case, PSU etc. to that. Even if this cost can be minimised, and can remain constant (in the case of the Athlon64s), it can be enough to swing the performance/price graphs around significantly.

    A 3000+ might be cheap, but factor in other costs and it might not be the fastest (indeed a quick check su

    They left out overclockability

    Yes, I know not everyone overclocks, but with chips that clock as easy as the A64's, you almost have to consider it. For example, the 3200+ came out as second place for performance/$ in every test, beat only by the 3000+. However, my 3200+ is currently running stable and cool at 2.6 Ghz and has a 512K cache.

    This puts it between the 4000+ and the FX-55. And my OC is very typical. As a matter of fact, it is low. Just about any venice 3200+ will hit that speed easily, and many will reach 2.7+Ghz. This puts the peformance/$ WAY up there.

    The 3000+ would probably also beat it. For some reason when I purchased my CPU, I forgot that I could run my RAM on dividers, so I ordered the 3200+ for its higher multiplier, which is completely useless with any modern motherboard, since RAM speed and CPU speed are independant of each other.

    So basically, I am saying get a 3000+, since it is the best chip out there for for performance/$, and almost matches the top of the heap for raw performance as well.

    It was an interesting article, with tons of good data (and, to their credit, they include the raw data without comment in the appendix (ok, it would have been a lot nicer if they included it in a spreadsheet-friendly format, but ...))

    Unfortunately, you can't do anything with a bare processor. You need a system to plug it in to, and that system costs money.

    If you assume that the disk/video/case/fans/power-supply/motherboard/OS package would cost $600 or so, then that would have the effect of adding $600 to the cost of each processor for a system that can do actual work. For example, in the 3Ds Max 7 Rendering Test, their calculated best performer was the Intel Pentium 4 630 or Intel Pentium D 820 -- relatively cheap processors.

    But, adding the $600 to the cost makes the best performer the Athlon 64 X2 3800 (the cheapest of the Athlon dual proc chips.) The other X2 chips round comprise four of the next five places as well.

    I think that adding a minimal system cost makes for a far more useful comparison -- and it does show the value of the new dual-proc systems. Not too surprisingly, the Athlon 64 FX chips still the worst price-performance solution -- they're just too expensive for what you get.

    When I buy a new CPU, I use a slightly different metric. Bang-for-buck is important to me, but so is raw performance. So I multiply the two together: (units of performance) * (units of performance per dollar) = (perf units ^ 2 / dollars). This tends to yield a maximum at a couple of speed grades below the highest available, which is the point at which the prices really start to take off.

    At current average energy prices (which are only increasing at this point), it costs about $7 a year for each 10 watts of continuous power. So if two processors' power consumptions differ by 50 watts, that's a savings of $35 a year. This might seem insignificant but it's enough to shift some of their results around.

    As energy prices climb the effect will only become more pronounced. Selecting a processor which is cheaper and faster but also happens to consume as much power as a small city is NOT a cost effective solution. Why blind ourselves to this?

    As previous stated, you must consider total cost of ownership. Pentium M desktops are not common yet but if you check the benchmark sites, you will see that the 2.1GHz Pentium M out performs the P4 running at 3.0GHz. And at 1/3 the power consumption. Intel Engineers knew the P4 was a dog when they ran the first simulation, but upper management didn't want to wait 2 months and spend millions to rework the core, so they used marketing to push the product and their marketing department should all get raises, because it worked. They used the lame excuse to techies that the pipeline is designed to work better at higher speeds, so the clock speed race had begun. When the PM are available I'm scrapping my P4, getting more perfomance, lower electric bills, lower medical bills (later in life from EMI)and leaving the dog behind. As for AMD, I am a big fan of the underdog with the superior product, AMD64, but it still is a little too pricey and sucks a lot of power also. It would be my fallback if the Pentium M does not make it to market soon. The Notebook manufactures want all of the PM production and are fighting to keep it. We will see.
