Geforce 6800


This is a photo of a Geforce 6800 GPU. I now own a variety of Geforce Cards:

Riva128
Riva TNT
Riva TNT2
Geforce
Geforce 2 Pro
Geforce 2 Ultra
Geforce 2 MX400
Geforce 3 ti200
Geforce 5200
Geforce 6800

This means that I only need a Geforce 4 and a new 7800GTX to complete the "Geforces through the ages" exhibit.

However, my ATi museum is in an appalling state:

MACH64 VT
RAGE3D Turbo
Radeon 7000
Radeon 9000

Pentium II 450Mhz


A new addition to my ever expanding Pentium II collection - a boxed (SECC 1) 450MHz. I now have -

233MHz - SL2HD
266MHz - SL2HE
300MHz - SL2HA
350MHz - SL2U3
400MHz - SL2S7
450MHz - SL2U7

leaving only the 333 Mhz to complete the collection.

The 450MHz Pentium II (Deschutes core) is odd in the same way in which the original PII 233MHz was released at exactly the same clock speed of it's predecessor, The Pentium 233MMX. You see, the Pentium III debuted at 450MHz, as the Pentium II ended at that speed.

The Deschutes core in this CPU - is an enhanced Pentium 2 core - one or two extra instructions were added to the Klamath core as well as the 100MHz front-side bus, and the higher clock speeds were made possible by a shrink to a 0.25u manufacturing process.

The later PIII Katmai cores were essentially Deschutes cores with one small difference a few more instructions (SSE - Streaming SIMD Extensions).
