1) The total x86 CPU market is divided 80% for business 
systems and 20% for retail systems;  also 38 million CPUs 
were sold in Q1
	x86 CPUs		
Business	80%	30.4	M
Retail	        20%	7.6	M
Total		        38	M
* units in millions if % not indicated

2) The retail consumers buy mostly low end systems : 90% 
Celeron and K6s vs only 10% Pentium III and Athlons.  The 
business market purchases as many high end systems (50%) as 
low end systems.  Subdividing the 30.4 M business systems 
and the 7.6 M retail systems gives :

	x86 CPUs			Celeron & K6	Pentium & Athlon	
Business	80%	30.4	M	50%	15.2	50%	15.2
Retail	        20%	7.6	M	90%	6.8	10%	0.8
Total		         38	M		22.0		16.0

From this, we could imply that total Pentium and Athlon 
retail systems in Q1 amount to only 800K units.  If your 
strenght is in retail, it's pretty hard to sell millions of 
high end systems (Athlons).

3) In Q1, AMD had only 5% of the business market but as much 
as 60% of the retail market.  Subdividing again the right 
end part of the above table gives :

AMD	K6	Athlon
5%	0.8	0.76
60%	4.1	0.46
	4.9	1.22
* units in millions if % not indicated

For comparison purposes, I find the following for INTC sales 
in Q1 :
INTC	Celeron	Pentium
95%	14.4	14.4
40%	2.7	0.3
	17.2	14.7
