What is the Difference Between Core Duo and Core 2 Duo?
🆚 Go to Comparative Table 🆚The Core Duo and Core 2 Duo are both dual-core processors from Intel, but they have some differences in terms of performance, cache memory, and overclocking ability. Here are the main differences between the two:
- Performance: The Core 2 Duo processor performs better than the Core Duo processor due to its higher overclocking ability.
- Cache Memory: The Core Duo processor has about 3 MB of L2 cache memory, while the Core 2 Duo processor has about 6 MB of L2 cache memory.
- Overclocking: The Core Duo processor can be overclocked up to approximately 3.12 GHz, while the Core 2 Duo processor can be overclocked up to approximately 4.0 GHz.
In summary, the Core 2 Duo processor is generally faster and more advanced than the Core Duo processor, with a higher overclocking ability and larger cache memory. However, the performance difference between the two processors may not be significant in all applications or tasks.
Comparative Table: Core Duo vs Core 2 Duo
The main differences between Core Duo and Core 2 Duo processors are their manufacturing process, die size, transistors, clock speeds, FSB frequency, and L2 cache size. Here is a comparative table highlighting these differences:
| Core Duo (Yonah) | Core 2 Duo (Merom) |
|---|---|
| Manufacturing Process: 65nm | Manufacturing Process: 65nm |
| Die Size: 90.3 mm^2 | Die Size: 144.9 mm^2 |
| Transistors: 151M | Transistors: 291M |
| Clock Speeds: 1.20GHz - 2.33GHz | Clock Speeds: 1.06GHz - 2.4GHz+ |
| FSB Frequency: 533MHz - 667MHz | FSB Frequency: 533MHz - 800MHz |
| L1 Cache Size: 32KB + 32KB | L1 Cache Size: 32KB + 32KB |
| L2 Cache Size: 2MB Shared | L2 Cache Size: 2MB - 4MB Shared |
| Pipeline Stages: 12 | Pipeline Stages: 14 |
| Decoders: 1 complex + 2 simple | Decoders: 1 complex + 3 simple |
| Maximum Decode Rate: 3 | Maximum Decode Rate: 4+1 |
| Reorder Buffer: 80 | Reorder Buffer: 96 |
Core 2 Duo processors generally offer better performance than Core Duo processors due to their larger die size, higher transistor count, and larger L2 cache size. However, the performance difference between the two is relatively small.
