Processor using the i586 microprocessor launched on 22th March 1993 and discontinued on 15th July 1999.

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

+== 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
