Hi,
I just bought a Thunderbird Athlon 1000 for a project.
I never had a "non XP" Athlon before (had a PIII back in 2001) and i was quite surprised to find that there were sometimes 2 models for the same frequency on Athlon Thunderbird.
Mine turns out to be a 1000C version (266 MT/s); but there is also a 1000B version (200 MT/s). The first Athlon 1000 Slot A is out of the socpe and cannot be compared since its cache model is different.
I was wondering if there were some performances differences between the B and C models (Could not find benchmarks online)
My "common sense" tells me that, given a fixed CPU frequency, a faster bus is generally better.
In my case, i imagine the following :
- Athlon 1000B : 1000 Mhz = 10 x 100 Mhz (200 MT/s)
- Athlon 1000C : 998 Mhz = 7,5 x 133 Mhz (266 MT/s) --> Better because of higher bandwidth
To advocate this, later Athlon XP used different P-Ratings do distinguish such differences :
- Athlon XP 2600+ : 2000 Mhz = 15 x 133 Mhz (266 MT/s)
- Athlon XP 2900+: 2000 Mhz = 10 x 200 Mhz (400 MT/s) --> Better because of higher bandwidth
I don't really think that the real perceived difference would be as big as 300Mhz as the p-rating suggest.
Around 2003 AMD started to exaggerate the p-ratings to catch on Intel P4 performance lead, but i still expect a noticeable improvement.
Am i wrong ?
