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 instuction s
- 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 hase several cores and supports hyper-threading
- Performance of Core i7 is about 1000 times bigger than the performance of Pentium 100
