View processor details Intel Pentium 66 'SX837'
Intel Pentium 66 'SX837'

The high-end choice in 1993. The fastest early Pentium which outperformed faster clocked 486's. Most early Pentium's one would see are from 1994, even though the Pentium was released in March 1993. Back in it's day it was too expensive for most people so not many Pentiums have been sold in 1993.

Intel Pentium 60 'SX835'

The classic Pentium at 60MHz. This is the first Pentium-class CPU along with its 66MHz counterpart.

Compared to a 486 the Pentium had several improvements including a superscalar architecture, 64-bit external data bus and a faster Floating Point Unit (FPU). The superscalar architecture allows the... > Read more

Intel Pentium 90 'SX957'

As with the Pentium 75's: the 90MHz model was also available with both integrated heat spreader as full ceramic packaging. The older CPU's have a gold colored heat spreader whereas the newer ones are fully ceramic.... > Read more

Intel Pentium 75 'SX961'

44 weeks older and uses a gold heat spreader for better heat distribution. Besides that it's not much different compared to the newer/regular Pentium 75.... > Read more

Intel Pentium 100 'SX963'

Same as this Pentium 100 except for the production date, sSpec number and core stepping. This one is older (17th week of 1995) and has core stepping C2.... > Read more

Intel Pentium 100 'SX970'

Dozens of Pentium CPU's exist and this is just one of them. I have more Pentiums running at 100MHz but they are all a tad different because the sSpec number differs.... > Read more

Intel Pentium 90 'SX968'

Same as the Pentium 75 but then a tad faster due to higher core clock frequency and front side bus. Especially the front side bus has a great impact on this CPU. It clearly jumps ahead on the 75.... > Read more

Intel Pentium 75 'SX969'

"Pentium done right" in general sense. The core only needs 3,3V instead of 5V like the Pentium 60 or 66. Because of this, and the smaller production size, the heat output is a lot less. Also upgradeability is better as the socket 4 topped out at 66MHz (133MHz for expensive Overdrive chips) where nor... > Read more

Intel Pentium 100 'SU032'

I don't see these Pentiums much :o. Normally they don't have a boxed heatsink and the ones that come by with boxed heatsink often have a silver like top. This one has blue letters indicating it's an Intel Pentium.... > Read more

View processor details Intel Pentium 120 'SY033'
Intel Pentium 120 'SY033'

Successor of the Pentium 100 that was on the market for a year before the Pentium 120 came. Despite it's slower bus it's quite a bit faster than the Pentium 100. A 60MHz FSB seems to fit the Pentium CPU quite well at these low (90MHz, 120MHz) clock frequencies. At higher clock frequencies (150MHz) t... > Read more

View processor details Intel Pentium 100 'SY007'
Intel Pentium 100 'SY007'

In March 1994 this CPU was launched along with the 90MHz model. The 100MHz part was top of the line and ran far ahead on every other x86 CPU. It's a tad faster than the 90MHz because both core and bus frequency are higher. It took Intel exactly one year to release the Pentium 120MHz and two years (M... > Read more

View processor details Intel Pentium 133 'SY022'
Intel Pentium 133 'SY022'

The Pentium 133 is the slowest Pentium that uses the P54CS-core. The P54CS is the successor of the P54CQS and is used in 133, 150, 166 and 200MHz (without MMX) models.... > Read more

View processor details Intel Pentium 166 'SY016'
Intel Pentium 166 'SY016'

For about 6 months this was the fastest CPU around. After that the 200MHz Pentium made it's debut and took the lead. At the time the Pentium 166 became affordable Cyrix and AMD had their 166MHz parts available. In general they were as good as the Pentium for business/office applications. In case you... > Read more

Intel Pentium 166 'SL25J'

First of all: this CPU is fake!

Some people take lower-end CPU's, modify (overclock) them to look like a faster model and sell them. This practice has been around for years and has been done quite recently as well. You can find fake 386 and 486 as well which often have something taped over that ... > Read more

Intel Pentium 200 'SY045'

The top-of-the-line Pentium processor. The only Pentiums that are faster are the Pentium MMX but they are not similar to the first kind of Pentium. I've never seen a Pentium 200MHz system running in real life as they were quite expensive back in the days this thing was new. By the time 166MHz and 20... > Read more

View processor details Intel Pentium 150 'SY015'
Intel Pentium 150 'SY015'

The Pentium 150 wasn't sold much because it had a slower FSB compared to the Pentium 133 and thus was less efficient and most people went for a Pentium 166 instead if they wanted performance. See the benchmarks that show the performance of the Pentium 150. Especially games (MDK, Doom and Quake) run ... > Read more

Intel Pentium 133 'SY022'

Same as this Pentium 133 except for the production date and the iComp index etched into the processor. This processor, which is about half a year newer then the other one, has the iComp2 index. iComp stands for Intel Comparative Microprocessor Performance. Th... > Read more

Intel Pentium Unfinished 'N/A'

An unfinished Pentium P54C CPU! An interesting piece; it's completely blank and doesn't have a 'die' fitted. On the pictures you can see what is located under the 'die' and clearly see the tiny leads that connect the 'die' to the 296 pins on the CPU.

I used the term 'die' a couple of times: a pro... > Read more
