Pentium 100
Processor using the i586 microprocessor launched on 22th March 1993 and discontinued on 15th July 1999.
Comparison of Pentium 100 (i586) and Core i7 (2024)
Pentium 100 (i586)
- It has relatively simple architectures with limited instruction set.
- Pipeline is less complex.
- Hyper threading is not available.
- There are no advanced optimizations for out-of-order execution.
- Simple memory model.
- Parallelism and thread processing: Pentium uses only one thread.
- Performance: Emulating Pentium 100 should be much more faster.
Core i7 (2024)
- Instruction set is much more complex (including SIMD extensions like AVX, AVX2, AVX-512).
- Several pipelines with out-of-order execution of instructions.
- Branch prediction.
- Hyper threading.
- And other advanced optimizations.
- Complex memory model:
- Several layers of cache (L1, L2, L3)
- Cache prefetching
- Speculative execution
- TLB (Translation Lookaside Buffer) for virtual memory
- Parallelism and thread processing: Core i7 has several cores and supports hyper-threading.
- Performance of Core i7 is about 1000 times bigger than the performance of Pentium 100.
