Great question! Let's compare the two options:

### Xeon E5-2643
- **Cores**: 8
- **Clock Speed**: 2.0 GHz
- **Cache**: 20 MB

### Xeon E5-2650
- **Cores**: 4
- **Clock Speed**: 3.3 GHz
- **Cache**: 10 MB

### Considerations for MATLAB and Signal Processing:
1. **Parallel Processing**: MATLAB can take advantage of multiple cores for parallel processing. More cores can be beneficial for tasks that can be parallelized.
2. **Clock Speed**: Higher clock speed can improve performance for single-threaded tasks.
3. **Cache Size**: Larger cache can help with faster data access and reduce latency.

### Recommendation:
Given that you're working with MATLAB and signal processing, **two Xeon E5-2643 processors** might be more advantageous due to the higher number of cores and larger cache size. This setup can better handle parallel processing tasks and large data sets.

However, if your specific tasks are more dependent on single-threaded performance, the **Xeon E5-2650 processors** with higher clock speed might be a better choice.

Ultimately, it depends on the nature of your workload. Do you have any specific tasks or benchmarks in mind that we can consider?
