will the 925x chipsets support the 64 bit processors? the article didnt seem to say anything about it, but im not quite sure. if it does, I may well upgrade.
No, you have it wrong. There is L1 cache - 16k instruction and 16k.. something else, the L2 cache is a data cache for commonly held stuff - it's like a local ram for the processor, but obviously you get a much higher bandwidth from it because its ultra low latency being onchip and ultra fast being ran at CPU speed. It's why P4EEs perform better at the same clock speeds and why Xeons have uber L2 cache - so it doesnt need to access the ram so often for common data. I think the 925x/915s support EM64T but you might need a BIOS update. There are EM64T processors out now so i assume so.
Intel is doing something about the memory bus problems by adding a second FSB to their new chipsets in order to stem the bleeding they take with processor scaling, so there wont be quite as bad of a performance hit in FSB speeds when using these new dual core Xeons. However, scalability is still always an issue in these Intel platforms; netburst was designed for speed, speed, speed, and as such, everything about the platforms was designed to support the highest clock speeds attainable. I dont think Intel made too much effort in the netburst architecture to give it future scalability. AMD on the other hand invested a lot of resources into making the K8 architecture highly scalable. This scenario sort of reminds me of the IBM 360 project, with all its twists, turns, and general crazyness.
Intel is going dual core basically because it realizes ONE CAN'T KEEP UP. Nice shot on cache there Bindi, the other is execution. Dual core is an interesting concept, how many recalls do you think it'll take before they get it right? Pardon my cynicism, but I have less and less respect for intel as the years pass...
Ah yea, execution. Brain fart earlier and couldnt remember. I dont think there will be any recalls since theyve moved their processor map ahead of schedule. I wonder what ICH7 will hold and if they'll finally integrate wireless into it??
While I dont like the majority of Intel products, I have to give them this; they do a damn good job of making a product reliable from launch. Im siding with Bindibadgi and having confidence that Intel is going to have something that works alright at the least from launch day; Intel wouldnt shoot themselves in the foot by launching ahead if the product didnt work.
Remember the 915/925 chipset recalls? I'm just going on prior track record when it comes to them... Once they played a losing game, they got antsy...
All too true. They've screwed the pooch one too many times, if they try again, it'll bite them. All the same, do they really think that they can get away with mainstream TEC as a STANDARD? Thank God my fellow forum members have sense, I fear our suppliers do not... (I've not been properly caffeinated... still stuck in rant mode...)
I dont agree. They have problems with their 90nm process, it's unfortunate but their northwood scaled incredibly and they are able to meet demand well. They dont perform clock for clock like AMD, true, but they do perform well in a large quantity of multimedia and office apps which Joe Public uses. I think they are still on damage control until we see a new core process arrive this time next year. Having said that, there's no way id use a prescott or even a dual core one, unless it's so powerful or full of features this somehow makes the heat issue acceptible. The recalls were a minor issue with a very early batch, NF4 silicon had similar problems and i still havent seen a VIA K8T890 board. It's all too easy to slate the big companies because they are first to the market, but they did have a set of PCIe chipsets out a good few months before anyone else.
According to Anandtech, early indications are an $80 price premium over single core chips. But until you see actual prices take it with a pinch of salt.
sweet thats not too bad. i can handle that. i think im going to hold off my my amd 64 system with pci express and build a dual core system
Id wait to see how the numbers fair before you do something that big. Two processors are not likely to show you any single application improvement-but multitasking will be improved. But thats about it.
I'll bet intel gets in cahoots with Thermalright before they go retail. I'd invest in heatpipes if I could, if they're not present I'd be stunned. Anyone else caught onto this is just a physical version of hyperthreading yet? Maybe about 5% more effective at full dual-load but in essence the same thing just hotter. And as it's been mentioned, no apps support (yet) it so it's pointless (at this time). I suppose when games finally are written to support HT/dual core intel may get a slight edge again but it'll be taken even further away by AMD once their dual-core parts hit shelves.
Actually, I think you misunderstood me. What I'm saying is that you really only need a maximum of 1 mb cache because you usually won't have enough instructions to fill all 2 mbs. That's why Extreem Editions only perform marginally better (less than 5 percent). So yes, I do have an idea of what I'm talking about. What you don't make up in extra instructions stored, you can make up in overclockability.
Let's not forget that only applies to enthusiasts really. Take the average joe in Best Buy and he probably won't have even HEARD of AMD, let alone know their 64-bit line kicks the pants off of Intel for gaming. At least in my area I've never seen an AMD advertisement on TV whereas I see intel ones all the time (the Blue Man Group ones, although it's been mostly Centrino recently not P4). The general public really just isn't as informed about things like this as we are I spent quite a while arguing with someone who now works at BB that DDR2 doesn't offer the slighest performance advantage over DDR1 yet, who then argued back that he read something to the contrary at THG (who, biased or not, I doubt simply makes up benchmark results). Then again this same person tried to convince me there's no reason to build your own computer and thinks I'm an idiot for doing so. Point being to the general public, it's "AMD who?" and "Intel has made a mistake??". They don't care who makes it or how hot it runs as long as it works.
