Reasons For

8 Reasons For
4% faster processor clock speed Edit
The HP 400 G2.5 SFF is a 3GHz processor clock speed PC. That's 0.1GHz faster than the Lenovo S500 SFF (2.9GHz). Read more

The speed that the microprocessor executes each instruction or each vibration of the clock. The CPU requires a fixed number of clock ticks, or cycles, to execute each instruction. The faster the clocks rate, the faster the CPU, or the faster it can execute instructions. Clock Speeds are usually determined in MHz, 1 MHz representing 1 million cycles per second, or in GHz, 1 GHz representing 1 thousand million cycles per second. The higher the CPU speed, the better a computer will perform.

A higher processor clock speed means that the computer can complete more calculations every second which means that applications will run faster.

Faster maximum turbo frequency Edit
The HP 400 G2.5 SFF is a 3.7GHz maximum turbo frequency PC. That's 0.3GHz faster than the Lenovo S500 SFF (3.4GHz). Read more

The turbo boost is an automatic, managed accelleration of the processor when one of the cores is overloaded.

Bigger internal memory Edit
The HP 400 G2.5 SFF is an 8GB memory PC. That's 4GB bigger than the Lenovo S500 SFF (4GB). Read more

A computer's memory which is directly accessible to the CPU.

A higher internal memory will allow the computer to run more quickly.

A lot bigger total storage capacity Edit
The HP 400 G2.5 SFF has a total storage capacity of 1TB, however the Lenovo S500 SFF is only a 500GB total storage capacity PC (500GB smaller). Read more

The total internal storage capacity is the space available for the computer to store documents, media and applications.

A bigger internal storage capacity means that you can store more applications, documents and media on the computer.

A lot bigger hard drive capacity Edit
The HP 400 G2.5 SFF has a hard drive capacity of 1TB, however the Lenovo S500 SFF is only a 500GB hard drive capacity PC (500GB smaller). Read more

The maximum storage capacity of the hard disk, usually measured in bytes e.g. GB.

A larger storage capacity will allow you to store more applications and documents on the computer.

A little faster on-board graphics adapter dynamic frequency Edit
The HP 400 G2.5 SFF has an on-board graphics adapter dynamic frequency of 1,150MHz, whereas the Lenovo S500 SFF is only a 1,100MHz on-board graphics adapter dynamic frequency PC (50MHz slower).
Six USB 2.0 ports Edit
The number of USB 2.0 ports on the HP 400 G2.5 SFF is six, but the Lenovo S500 SFF only has two USB 2.0 ports. Read more

Number of USB 2.0 ports (connecting interfaces) in the device. USB 2.0 was released in April 2000 (now called "Hi-Speed"), adding higher maximum signaling rate of 480 Mbit/s (effective throughput up to 35 MB/s or 280 Mbit/s), USB 2.0 ports are usually black.

2.1kg lighter Edit
HP 400 G2.5 SFF is 4.5kg heavy, but the Lenovo S500 SFF is a 6.6kg heavy PC (2.1kg heavier).
2 Reasons For
Bigger maximum on-board graphics adapter memory Edit
The Lenovo S500 SFF is a 1.74GB maximum on-board graphics adapter memory PC. That's 0.72GB bigger than the HP 400 G2.5 SFF (1.74GB).
1 shops are selling it
The more shops stock the product, the greater competition amongst shops to keep prices low.

Reasons Against

2 Reasons Against
Hugely smaller maximum on-board graphics adapter memory Edit
