We can better compare what are the technical differences between the two processors.

Suggested PSU: We assume that we have An ATX computer case, a high end graphics card, 16GB RAM, a 512GB SSD, a 1TB HDD hard drive, a Blu-Ray drive. We will have to rely on a more powerful power supply if we want to have several graphics cards, several monitors, more memory, etc.

Price: For technical reasons, we cannot currently display a price less than 24 hours, or a real-time price. This is why we prefer for the moment not to show a price. You should refer to the respective online stores for the latest price, as well as availability.

We see that the two processors have an equivalent number of cores, the turbo frequency of Intel Core i7-870 is bigger, that the PDT of Dual Intel Xeon E5450 is lower. The Intel Core i7-870 was started more recently.

Performances :

Performance comparison between the two processors, for this we consider the results generated on benchmark software such as Geekbench 4.

In single core, the difference is -14%. In multi-core, the differential gap is 28%.

CPU-Z is a system information software that provides the name of the processor, its model number, the codename, the cache levels, the package, the process. It can also gives data about the mainboard, the memory. It makes real time measurement, with finally a benchmark for the single thread, as well as for the multi thread.

In single core, the difference is 7%. In multi-core, the differential gap is 33%.

Cinebench R15 evaluates the performance of CPU calculations by restoring a photorealistic 3D scene. The scene has 2,000 objects, 300,000 polygons, uses sharp and fuzzy reflections, bright areas, shadows, procedural shaders, antialiasing, and so on. The faster the rendering of the scene is created, the more powerful the PC is, with a high number of points.

In single core, the difference is 12%. In multi-core, the differential gap is 39%.

Cinebench R20 is a multi-platform test software which allows to evaluate the hardware capacities of a device such as a computer, a tablet, a server. This version of Cinebench takes into account recent developments in processors with multiple cores and the latest improvements in rendering techniques. The evaluation is ultimately even more relevant.

In single core, the difference is -9%. In multi-core, the differential gap is 54%.

PassMark is a benchmarking software that performs several performance tests including prime numbers, integers, floating point, compression, physics, extended instructions, encoding, sorting. The higher the score is, the higher is the device capacity.

On Windows 64-bit:

In single core, the difference is -29%. In multi-core, the differential gap is 4%.

On Linux 64-bit:

	Geekbench 4 — Multi-core & single core score — Linux 64-bit
Dual Intel Xeon E5450	1. 963 10.256
Intel Core i7-870	2.983 9.139

In single core, the difference is -34%. In multi-core, the differential gap is 12%.

On Mac OS X 64-bit:

In single core, the difference is -32%. In multi-core, the differential gap is 7%.

Geekbench 4 is a complete benchmark platform with several types of tests, including data compression, images, AES encryption, SQL encoding, HTML, PDF file rendering, matrix computation, Fast Fourier Transform, 3D object simulation, photo editing, memory testing. This allows us to better visualize the respective power of these devices. For each result, we took an average of 250 values on the famous benchmark software.

On Windows:

In single core, the difference is -23%. In multi-core, the differential gap is 19%.

On Linux:

In single core, the difference is -21%. In multi-core, the differential gap is 8%.

On macOS:

In single core, the difference is 33%. In multi-core, the difference in terms of gap is 6%.

Geekbench 5 is a software for measuring the performance of a computer system, for fixed devices, mobile devices, servers. This platform makes it possible to better compare the power of the CPU, the computing power and to compare it with similar or totally different systems.
