Looked at the Power or PowerPC ISA recently? RISC was created not because a reduced instruction set is inherently better, but because it allowed for a number of technologies such as pipelining, branch prediction, caching, and so forth to be implemented. Every single one of those is in x86 architecture now. Sure, the ISA is still a mess, but it's a better price/performance than anything else out there.

      Simple really. AMD feared that Intel was about to release the next revision of the P4 aka. Prescott. The 940-pin FX was an attempt to get something out the door ASAP.

      Unfortunately that means that some people might be caught at a loose end when it comes to upgrade time, but that is not clear cut at this stage to my knowledge.

    2. Re:Still not convinced by Hoser+McMoose · · Score: 4, Informative

      The marketing of the Athlon64 FX has become a bit confusing. It kind of made sense for the initial launch to combat a precieved weakness of the design compared to Intel's P4 though. With the P4 you get up to 6.4GB/s of memory bandwidth, while the first Athlon64 would only have 3.2GB/s of memory bandwidth. Now, it turns out that the extra bandwidth doesn't actually buy you much on most applications, but this was seen as a weakness, hence the Athlon64 FX. With Intel bringing out the P4EE to compete with the FX, now AMD might need to keep the chip, even if it isn't a worthwhile product (The P4EE isn't a worthwhile product either).

      *Is it really a good idea to have the memory controller on the CPU?

      Yes, yes it is a good idea. A VERY good idea in fact. Memory latency has only improved by about one order of magnitude in the past 15 years. Meanwhile everything else in the system has gone up by at least two orders of magnitude. Virtually everything that is being done in CPU design these days is to hide memory latency (larger caches, out-of-order executation, branch prediction, even SMT).

      Integrating the memory controller reduces latency by 20-30%. At 2.0GHz this makes a BIG difference (this is the main reason why a 2.0GHz Athlon64 is faster than a 2.2GHz AthlonXP), at 4 or 5GHz the difference will be huge.

      but it hasn't lowered mainboard costs

      You can buy new Athlon64 motherboards for only $100, only 3 months after the chips release. It took ages for Athlon or P4 motherboards to reach that price point. What's perhaps even more impressive is the dual-processor boards that are only $200. In short, it HAS reduced motherboard costs, whether you've noticed or not. It also means that ALL Athlon64's support ECC, chipkill and a few other nifty reliability features, regardless of how badly VIA screws up their chipset design.

      *Why in the world introduce an AthlonFX based on Socket 940, especially at the outrageous price, when you're moving to socket 939 imminently?

      The Athlon64 FX was a bit of a last minute decision I believe. They found a marketing weakness and wanted the quickest and easiest solution they could find. The answer? Sell your server chip as an "enthusiast" chip. Intel did exactly the same thing for the same reason with the P4EE.

      Also, it's actually VERY normal to switch sockets soon after releasing a new processor. Intel's upcoming Prescott will use Socket 478 for only about 6 months before switching to socket 775. The original P4 used Socket 423 for a very short time before switching to socket 478. The original Athlon used Slot A for a year or so before switching to Socket A. The PIII came out in Slot 1 form but then switched to Socket 370 about a year later. The Celeron followed the same path a couple years before.

      I think it would have been more of a slam-dunk as a platform and a "brand" to release Athlon64 as all dual-channel, all Socket 939 (or some standard), and left Opteron as the high-end platform. Any other takers?

      In retrospec that might seem like a good idea, hindsight is 20-20 after all. However the original split of ALL Athlon64 chips being socket 754 and ALL Opteron's being socket 940 seemed to make the most sense when AMD was desigining them. It wasn't until market conditions changed and a new perceived weakness was discovered that AMD felt they need a consumer chip with a 128-bit wide memory bus. By that time the chip was already late to market and designing a new socket would have added more delay to the equation.

      There's also the question of budget chips. AMD hopes to move their entire product line to the Athlon64/Opteron platform by the end of 2004. That means they need a budget chip, and socket 939 with it's 128-bit wide memory bus is problematic for that. Hence the continued existance of Socket 754 and the AthlonXP for that platform.

Within a few percentage points, every 2600+ CPU will perform equally, regardless of its core, amount of cache, socket, memory lines, clock frequency, etc. That's the whole point - you don't have to know. If you're "in the know", you can look at individual 2600+ CPUs to see which one has more of what will help you in the specific applications you use. If you're a general user, then 2600+ is the only thing you need to know. How many people buy a 3.06GHz P4 instead of a 3.00GHz P4 because they think the former is faster? The clock frequency alone belies the fact that the higher FSB on the latter CPU will actually make it perform far better on nearly every application. AMD is trying to hand you the whole package in a single number to simply the buying process for everyday people.

      The fact is, neither AMD nor Intel are telling the whole performance truth, nor could they do so. The only way to do that is to educate consumers about CPU mechanics, latency, IPC, L1/L2 cache, cache hits and misses, branch prediction, pipeline stages, and so on. The average consumer (hell, the average geek) can't understand half of these things. Thus, Intel has chosen to show the clock frequency of its CPUs, and AMD has chosen to use performance ratings that give consumers a performance index relative to the Athlon's Thunderbird core. Neither system is perfect, but neither system is more imperfect than the other, in my opinion.
