Dual Core Computers

The 945 and 955 chipsets from Intel are due to launch in a few months. With them come the first dual-core processors from Intel: the Pentium 4 840, 830, and 820. According to anandtech.com, Intel is charging $80 more than the equivalently clocked single-core processor. They will be 64-bit enabled, like the rest of Intel's processors starting in Q2.

AMD's dual-core Opterons will launch sometime this summer. Dual-core Athlon 64s are not expected until Q3.

You can buy the new 533MHz FSB Centrino laptops right now. AMD is launching their Centrino equivalent, dubbed Turion, next week. Dual-core Centrino laptops are not scheduled to be available until 2006.

Intel is letting select members of the press experiment with a prerelease version of the new Pentium 4 840 EE. It is clocked at 3.2 GHz. The fastest 800 MHz FSB Pentium 4 currently available is clocked at 3.6 GHz; the fastest Pentium 4 EE is clocked at 3.73 GHz.

On single-threaded workloads like games, the dual core 840 is slower than the 3.73 EE in proportion to the frequency discrepancy.

The 840 EE will have Hyperthreading turned on for a total of four concurrent threads (2 physical processors, 4 logical processors). Other Pentium D CPUs will have Hyperthreading turned off.

AMD has launched their multisocket dual-core Opteron line. The dual socket dual core Opteron line will be available in a month.

OEM Athlon 64 X2 (the new marketing name for desktop dual core from AMD) will be available in Q3. Retail Athlon 64 X2s will be available in Q4.

I have to revise my earlier statement. Intel's adder for dual-core apparently starts at $78 and goes to $312 for the top bin. AMD's adder for dual-core starts at $265 and goes to $358 for the top bin.

Anandtech previewed Athlon 64 X2 performance using the Opteron 875 launched today. They have interesting benchmarks using real-world multitasking scenarios, like surfing while backing up a DVD. These benchmarks show the benefit of having a second core to desktop users.

Ok, you guys got down how to do 2, now go make me 4 or 8 on a die. (I'm not counting virtual CPU's created by HT). I need more processing power.

Current multicore implementations are limited by the process technology. Both 90nm dual-core general purpose processors from AMD and Intel are in the range of 200 square mm. Sony-IBM get around this limitation for Cell on 90nm by reducing the complexity and performance of each individual core so they can fit 8 processors on a single die of more than 210 square mm.

Each successive process generation can squeeze about twice as many transistors on the same size die.

ok, scale your process technologies faster then. If Intel needs help, I can think of a certain company I work for that could possibly help...

OEMs are receiving their first Athlon 64 X2s now. Retail dual-core Athlon CPUs are not expected for a while yet.

An interesting item to note is that there will be no more single-core Athlon 64s from AMD. They will continue selling the premium-priced Athlon 64 FX line for gamers. However, they are treating the Athlon 64 X2s as their new top bin; expect the dual-core CPUs to slide down the stack with time.
