Die Heise Meldung "Weiter Verwirrung um 90-Nanometer-Prozessoren von AMD " verweisst auf folgenden sehr interessanten Artikel des Moderators Greyhouns auf forums.amd.com.
Es geht um die Zuordnung der S754 Semprons.
"Since a number of people have requested info on the upcoming 754-pin Sempron parts, I will provide this information here.
This post deals with 754-pin Semprons ONLY
Keep in mind that AMD has NOT officially released any new 754-pin Semprons yet, nor do they provide any specs or datasheets for these parts at present.
ALL info posted below is to the best of my knowledge - I do NOT have any official datasheets to back this up at present.
90nm SOI 754-pin Sempron processors
Currently, these are based on the 754-pin 90nm SOI core codenamed 'Oakville' (rev. DH8-D0) and will return CPUID '10-F-C-0'.
This is the same 'Oakville'-core that is used on the new 90nm SOI Mobile Athlon 64 parts, but with AMD64 and part of its (512KB) L2-cache disabled, leaving a 32-bit processor with 256KB or 128KB of functional L2-cache.
Sempron 2600+, OPN: 'SDA2600AIO2BA', 1.60GHz, 1.40V Vcore, 69°C max temp, 128KB L2-cache, 62W TDP
Sempron 2800+, OPN: 'SDA2800AIO3BA', 1.60GHz, 1.40V Vcore, 69°C max temp, 256KB L2-cache, 62W TDP
Sempron 3000+, OPN: 'SDA3000AIO2BA', 1.80GHz, 1.40V Vcore, 69°C max temp, 128KB L2-cache, 62W TDP
Sempron 3100+, OPN: 'SDA3100AIO3BA', 1.80GHz, 1.40V Vcore, 69°C max temp, 256KB L2-cache, 62W TDP
130nm SOI 754-pin Sempron processors
They're based on the 754-pin 130nm SOI core codenamed 'Newcastle' (rev. DH7-CG) and will return CPUID 'F-C-0'.
This is the same 'Newcastle'-core that is used on the 754-pin 130nm SOI Desktop Athlon 64 parts, but with AMD64 and part of its (512KB) L2-cache disabled, leaving a 32-bit processor with 256KB or 128KB of functional L2-cache.
Sempron 3100+, OPN: 'SDA3100AIP3AX', 1.80GHz, 1.40V Vcore, 70°C max temp, 256KB L2-cache, 62W TDP
Determining whether you have a 90nm or 130nm part
The Sempron 3100+ is the only 754-pin Sempron processor where this problem is present.
Generally, you can determine what kind of CPU-core you have by looking at your processors' OPN (Ordering Part Number) - it's printed on the metal heatspreader that covers your processor (you can look at it through the retail-box's clear plastic window):
'SDA3100AIP3AX' -> Newcastle, 130nm SOI, DH7-CG
'SDA3100AIO3BA' -> Oakville, 90nm SOI, DH8-D0
As you can see, the OPN-suffix (aka 'part definition'), i.e. the last two characters of your processors' OPN will tell you what model and revision it is.
Socket 754 90nm SOI (Oakville) Sempron Retail/Boxed parts will have an OPN (Ordering Part Number) like this: 'SDA3100BABOX'
If your processor is already installed, you can use a CPUID-utility like CPU-Z or WCPUID to identify it:
A 754-pin with the 'Newcastle'-core will return CPUID 'F-C-0' while a Sempron with the 'Oakville'-core will return CPUID 'F-C-0' and extended CPUID 'F-1C'.
Why do you say it uses the 'Oakville'-core - why not the 'Palermo'-core that is on the official roadmap
Simple. The CPUID of these parts is the same that is returned by one of the new 90nm Mobile Athlon 64 processors which have the 'Oakville'-core.
Also, it makes sense to design and produce only one core and enable/disable parts of it as needed to offer different products...this way, AMD saves a lot of costs for producing and validating a whole new core.
Furthermore, the upcoming 'Palarmo'-core (Sempron) as well as the upcoming 'Venice'- (Athlon 64) and 'Toledo'-cores (Athlon 64 FX) will all be E-revision parts whereas the new 754-pin Semprons are D-revision parts. "
