Quote - Likely because of the cache-size; past AMD processors had much less cache than Intel processors and the less cache you had, the more any comparison you did between 32 and 64 became a comparison of RAM-speed (which is essentiallly the same for 32 and 64).

The comparison that I did was at CPU level, the execution speed of the instruction assuming all the data you need is in level 1 cache.

Cache size importance depend on the application. If all your code and data is able to fit in the cache level 1 your app will run at CPU speed. If all your code and adat is able to fit in cache level 2 the app will run a little slower.

The problem is that the caches are very small, 1MB or less, so a simple nude Vicky4 is unable to fit in any cache. Accessing Vicky4 data will always be at memory bus speed and the caches in this case have an adverse effect because the overhead of cache miss and useless cache filling.

CPUs were not designed to run 3d applications, it were designed to play mp3, watch some video or play with Microsoft Office and so, caches work pretty well for this kind of application.

Stupidity also evolves!
