Duron: Socket 1.-Supports one dual-channel memory controller, but depends on the chipset. But due to the design of bus / clock synchronous, will be unable to take more than 50 of the bandwidth in this configuration. 2.-You can not run 64-bit code. 3.-It is offered principally 64Kbytes of L2 cache. 4.-faster version: 1’80GHz. 5.-From the oldest to the newest, the kernels used are: Spitfire, Morgan, Appaloosa, Applebred. 6.-Longevity in the market: Virtually none. With the release of the Sempron family expected total disappearance. 7.-overclockability: Some users claim to have achieved speeds of up 2’40GHz Duron processor core based Applebred and air cooling. Nobody seems to have proven liquid cooled. 8.-Best motherboard: Abit NF7 probably-S 2.0 is the best for Athlon XP processors. 9.-SMP capacity: it is theoretically possible but would need modifications to the bridge. Athlon XP: Socket A 1.-Supports one dual-channel memory controller, but depends on the chipset. But due to the design of bus / clock synchronous, will be unable to take more than 50 of the bandwidth in this configuration. 2.-You can not run 64-bit code. 3.-It is offered principally 512KBytes L2 cache, while older versions, such as the Thoroughbred-B, came with 256K. 4.-faster version: 3200 (2’20GHz). 5.-Del oldest to newest, the kernels used are: Palomino, Thoroughbred A, Thoroughbred B, Barton, Thorton 6.-Longevity in the market about 16 months.AMD will supply them in the second quarter of 2005 and is expected to empty stocks at the end of that year. However, it is a powerful processor, reliable and able to move many current games. Affordable systems should keep in mind this processor. 7.-overclockability: with air cooling, to 2’40GHz. With liquid cooling, to 2’70GHz. 8.-Best motherboard: Abit NF7 probably-S 2.0 is the best for Athlon XP processors. 9.-SMP capacity: it is theoretically possible but would need modifications to the bridge. Sempron: Socket A 1.-Supports one dual-channel memory controller, but depends on the chipset. But due to the design of bus / clock synchronous, will be unable to take more than 50 of the bandwidth in this configuration. 2.-You can not run 64-bit code. 3.-It mainly offers 256Kbytes of L2 cache, while the 2200 version has 512K and 128K 2400 version. 4.-faster version: 2800 (2GHz). 5.-From the oldest to the newest, the kernels used are: Thoroughbred B, Thorton. 6.-Longevity in the market have recently emerged to replace the Duron. Remains to be seen its sales capacity, but users have reported good compatibility with Socket A boards However, AMD plans do not include any review of the nuclei. 7.-overclockability: air-cooled until 2’20GHz. With liquid cooling, to 2’50GHz. 8.-Best motherboard: probably the Abit NF7-S 2.0 is the best. A recent update of the BIOS can easily adapt to the new processor. 9.-SMP capacity: it is theoretically possible to be based on the Thoroughbred core. However, its encapsulation protects the bridges that would change. Sempron: Socket 754 1.-Not allowed to use memory in dual channel configuration.
