Not really.
Since the launch of the Athlon 64 from AMD, Intel has been playing catch up (that's a good while, the A64 is actually getting old now). Intel totally shot themselves in the foot with the Netburst design (the P4). Netburst was suppose to go all the way up to 10Ghz! But Intel realized that they just coulnt do that (heck, they didnt even break 4Ghz). So they had to bring something up fast to meet AMD's far superior approach, enter Pentium M's desktop part: Conroe.
The Pentium M has been around for a good while now. Its actually based around very old technology (actually, the basics in CPUs today are extremely old in computer lifetime) in the P6 design (first Pentiums), though its called the P8 because it has indeed gone through many changes since then. The focus is more work per clock cycle rather than going all out for clocks. This works very well as right now its easier to throw more silicon at a problem than doing process noide races for more hertz.
The Conroe is a evolution of this design. It has very short and wide pipelines, so it does a lot of work per clock cycle, it also has a huge amount of cache (something that makes me a be worried about its lasting power though). The Conroe will be known as the Core 2 on the market, it'll be fast, very fast, I'm talking around a 25% increase over current A64's. It'll also run very cool and use little power, this is all part of the design goal.
Right now Intel is using their massive faberication capacity to price its processors extremely low. This is why they have $110 dual core processor in the 805, which is really the same basic chip as the highest end dual cores from Intel, this is why people like Cheese with just stock cooling have no issues OC'ing the processor to 3.5Ghz and run all day long. Its a great value, and its because Intel has to sell these till Conroe comes out, then these will leave the market pretty much, think of the $110 price as stock clearing. Its cheaper to sell them at extremely low prices than to keep them in storage at normal prices.
Conroe will be here in a matter of weeks now, possibly days.
K8L from AMD is basically a A64 on MASSIVE amounts of steriods. Its extremey beefy and will be a native quad core design. If you want some extreme tech specs here you go:
0. Native quad core
1. Hypertransport up to 5.2GT/s
2. Better coherency
3. Private L2, shared L3 cache that scales up.
4. Separate power planes and pstates for north bridge and CPU
5. 128b FPUs - see 14,15
6. 48b virtual/physical addressing and 1GB pages
7. Support for DDR2, eventually DDR3
8. Support for FBD1 and 2 eventually
9. I/O virtualization and nested page tables
10. Memory mirroring, data poisoning, HT retry protocol support
11. 32B instead of 16B ifetch
12. Indirect branch predictors
13. OOO load execution - similar to memory disambiguation
14. 2x 128b SSE units
15. 2x 128b SSE LDs/cycle
16. Several new instructions
Coprocessors:
media processing
JVM/CLR acceleration
TOE, XML or SSL processing
Basically, really fast. How much faster than Conroe? Unkown, but by then we'll see an updated version of Conroe and also quad core from Intel.
So yeah, a break down of the current consumer CPU market, the server one is REALLY fun! Some of the stuff from Sun is simply amazing to study like Ultra Sparc T1 from Sun which uses the Nigeria architecture, that chip packs in 8 cores each being able to handle 4 threads at once! Also, Intel says they'll have a 32 core processor by the time 2010 rolls in. So fun!
Dyn, for a link just go look at the HardOCP front page.
