What's Up With the New Intel Numbering Scheme?

[MrControversial]

I guess they pretty much hit the wall as far as heat/MHz goes and since they'll be going dual core, they want to get away from the MHz thing because it won't be a marketing advantage anymore. Am I wrong?

 

[hopejr]

I've been wondering this too.

Partly because they have been hitting scaling issues with their new core (prescott) and they need to differentiate between the minor revision that they are doing

5xx series - p4 upto 3.8, prescott core, 1mb l2 cache
5xxJ series - p4 upto 3.8, prescott core, 1mb l2 cache, NX bit
6xx series - p4 upto 3.8, prescott core, 2mb l2 cache, NX bit, EM64T (64-bit cpu)
8xx series - Pentium D - Smithfield core, 2mb L2 cache,Dual Core, NO HT(hyperthreding), cant remember if it is 64-bit as well (something tells me it is)

Pentium D is just 2 Prescotts slapped together, so it has EMT64 I am fairly sure.

I thought intel's dual cores will have ht. In that demo with the Unreal 3 engine and the 512mb cards, they used a dual core and it showed four processes or whatever in the cpu usage thing. Would'nt that mean ht?

 

[Dahak]

They are releasing the Pentium D Extreme Edition which has 2 cores and ht which is why there are 4 processes. The standard Pentium D will only have the 2 cores, and no ht

What's the "NX bit" ?

 

[Dahak]

Quotted from Xbit Labs, explained better that i could

NX bit (Non-Execute) which prohibits the execution of code that is stored in certain memory pages to prevent buffer-overflow attacks

So, in a nutshell, the NX bit protects your computer against viruses and other dangerous programs that start up from those memory areas that are intended by the OS and other applications to store data (not code)

Well I've seen 3 Pentium D's first hand in testing, a 2.8, 3.0, and a 3.2. All had HT The 2.8 was 85watt and the 3.0-3.2 were both 130watt. So far testing on a 945chipset board wasn't very impressive, but non of the benches were made for dual core cpu's, and won't know how they overclock until I get one home to play with..😉

The are following the AMD madness now

3100+ Sempron is somehow faster than a 2800+ A64 or a 3000+ A64

All a marketing plan

It was so much simpler when they just went by Mhz

 

[ribbon13]

AMD can't go by MHz because they do a lot more per cycle than Intel

I know, I was just reminiscing back to a simpler time 😛

No it wasn't.
