In an AMD Athlon 64 X2 5000+ What does the 5000+ mean?
Answers:
Amd has allways been in competition with Intel. These numbers show you that if you buy this modell, it will be as fast (or even faster, that's what + stands for) then if you bought an Intel CPU running at 5 Ghz (or 5000 MHz).
I know this is a silly thing to do from AMD, but it's their policy.
no
It's the "rated performance" of the processor--in other words, while it doesn't run at 5000 MHz (or 5 GHz), it is rated to run that fast.
The higher number, the better.
In the old days, the large number with many zeros mean the clock speed of the microprocessor (how often a processor would execute commands, per second). Back in the days there were 100MHz machines, 500MHz etc. All the way up to 3GHz which meant 3 billion operations per second, in simplistic terms.
At some point few years ago the clock speeds hit the wall due to the electrical limitations of the semiconductor technology. However, the performance of these processors has continued to improve due to the architectural innovations.
Since AMD was first to hit that wall with their architecture while Intel continued to push forward with the higher clock speeds, they needed to come up with a measure of their performance: since their newer processors could outperform then current 3GHz Pentiums, they decide to call them AMD 3200+. And so it went -- this "relative" performance measure "stuck", and now AMD quotes their performance relative to, let's say, a 1GHz Pentium. i.e. AMD Athlon 5000+ in theory outperforms a 1G Pentium IV by a factor of 5. Is this accurate? By no means. But it offers a relative measure of performance.
Once upon a time, there was a direct correlation between the model number and the rated MHz/GHz Intel equivalent. That ended with the AMD 64 line of processors, about 3 years ago. AMD has disengaged their models numbers from that system, because the correlation is more and more inaccurate. Apples and oranges comes to mind. The 5000+ is higher in performance than the 4800+, in speed tests, and lower in performance than the 5600+.
As for a direct comparison to Intel CPUs, that is no way to directly compare speeds, since the two companies use different memory-handling architectures. An AMD CPU has its memory controller located on the chip, while an Intel memory controller is located on the motherboard. The Intel chips suffer from memory lag, even though the processor is a bit faster. AMD chips handle memory and 3D processing faster, while Intel chips generally do better in business apps.
