quite different results.
A built-in chess benchmark helps you measure the chess specific performance of your
hardware. In order to make the results reproducible it is always conducted with a
standard chess engine.
The results of the chess benchmark test depend to a great extent on the size of the
hash tables. It also varies according to the number of applications you have running in
the background. You should use the test to check the effectiveness of your current
configuration.
Typical chess benchmark values for a 2.6 GHz Pentium with 128 MB hash tables is 1.4
(i.e. it is 1.4 times faster than a P3 running at 1 GHz. You should get a kilonodes per
second value of abround 600. The Centrino and Athlons will give you much better
values, since they are better suited to the kind of (integer) calculations used by chess
engines.
The nodes-per-second value of the chess benchmark gives you the number of
positions the engine is generating and evaluating per second. This value (in “kilo
nodes”) is independent of hash tables, and depends almost solely on processor speed.
Some engines will give you up to two million nodes per second on modern hardware.
But remember that the lower node counts of some engines does not necessarily mean
that they are weaker. Usually they are simply processing more chess knowledge.

Fritz Chess Benchmark.exe
On the program DVD there is a utility called Fritz Chess Benchmark.exe. This is what is
running during a chess benchmark as described above. The utility can also be started
independently, which means you can copy it onto a memory stick and run it on
different computers when you are purchasing a new one. This will help you make sure
you select a machine that gives you good values for chess calculations.

3.8.23 Engine Interface
The program’s engine interface has been adapted to the latest Windows
specifications, for example Windows 8/10.
This means that all current and future engines will don be stored in the folder
\Program Files\Chessbase\Engines but in \Program Files\Common
Files\Chessbase\Engines.
This is the folder where the new engine and the latest version of Crafty will be
installed.
Older chess engines installed by previous program versions will remain in the folder
\Program Files\Chessbase\Engines.

UCI Engines
UCI engines can still be installed in any folder in any partition anywhere on the
computer.
