In this video, we push the limits of Socket 7 by benchmarking the legendary Intel Pentium "Tillamook" 266 overclocked to 350 MHz on a modified ASUS P5A-B motherboard.

The Tillamook is a mobile Pentium MMX built on a 0.25-micron process, allowing it to run cooler and clock higher than almost any other P55C. But can it actually beat the AMD K6-2 and K6-III in real-world gaming? We put it to the test against the K6-2, K6-III, Pentium II, and Celeron across a suite of classic benchmarks.

Benchmarks Included:
- 3D Games: Unreal, Quake, Quake II, and DOOM
- Synthetics: 3DMark99 and SpeedSys

Is this the ultimate "hidden gem" for Super Socket 7 builds, or does the Slot 1 architecture still reign supreme? Let’s dive into the results!
