AMD Duron

128K L1, 64K L2

Socket A

3DNOW!

Fastest budget chip on the market, now available @ 1Ghz+ 

Info from

  • Chip manufactured with 0.18 micron technology with copper interconnections

  • Spitfire core based on Athlon architecture with 25 million transistors and 100sq.mm core size

  • Works in specially designed mainboards for 462-pin Socket A

  • High performance 100MHz EV6 system bus

  • 128KB L1 cache (64KB for data and 64KB for instructions)

  • 64KB L2 integrated on-die cache working at the full processor frequency

  • 1.5V Vcore

  • 3DNow! SIMD-instructions


The Morgan Core - AMD have reached the 1Ghz with its budget chip - the Duron. To do this the older spitfire core was axed in favour of a new, slightly larger core they call the Morgan core. Features in the the core have made the transistor count rise from 25Million to 25.18 Million. The major enhancements are signified below.

  • Data Prefetch

  • SSE Support

  • Improved L1 TLBs

  • On-die Thermal Diode

Data Prefetch - The process where the CPU "predicts" what data it will require before it is requested. The data is fetched from main memory and placed into the CPU's cache. This gives a marginal speed increase. It also uses more of the FSB bandwidth available to it. DDR memory has more of an effect now than it used to mainly because of this. 

SSE - Included in the new Duron package is the ability to use SSE (Streaming SIMD Instructions) Yes the instruction set that is used in the Intel chips is now available in the Duron. Even when playing games with SSE support you will be shown the SSE enhanced logo's. AMD dubs this technology 3DNOW! Professional.

Level 1 TLB's - Translation Look-aside Buffers. In would go against what this site stands for if I decided to explain this in detail. for more info on this goto this article at AnanTech. The basics is that it allows a higher hot rate by the CPU to access memory address' in the TLB.

On-die Thermal Diode - A nice little feature that has been a long time coming. The thermal diode reads the core temperature of the CPU. Not a big deal you say but when used correctly it can be used to slow down the CPU should it get to hot or even stop it if it gets to a critical temperature. This should lengthen the CPU's life span. Intel have been using this for quite a while now.  

By far and away the best value chip currently available on the market. It is based around the Athlon Thunderbird core to give it supreme performance. The main difference in the High end Athlon CPU and this the budget Duron chip is the level 2 Cache. The Duron only comes with 64Kb which effectively slows it down. But you try telling that to the benchmarks. The Duron really does have great performance at a low cost. If your looking for a respectable system which can handle the games as well, then this is the chip to build it round. 

The Duron however does have the advantage of not having unified L1 and L2 cache, therefore the L1 and L2 cache will never have to contain the same data. What this achieves is an effective L1 cache of 192K, only that 64K of it is on the die.

 How does the Duron live up to the other Processors on the market? what are the relative specs like? find out with our CPU Comparison Guide.

 

The Athlon has now been surpassed by the release of the Athlon Thunderbird and the Athlon XP. The XP takes the reigns as the fastest processor on the market and still cheaper than the P4. However the motherboards and cases required have not followed suite and cost a lot more still. Good option for anyone wanting power.
