[DUG] delphi is fast-very fast

[Jolyon Smith]

You code wouldn't even rate on the benchmark!  The test hardware (Toshiba
T5800 laptop, in case you missed it) doesn't support the specific graphics
card you would be relying on!

 

I think you've misunderstood the object of the exercise.

 

It wasn't about finding the fastest way to do something using whatever
hardware was necessary.  It was about comparing the relative performance of
commonly used languages on a given OS (Windows) and hardware (32-bit x86)
combination.

 

 

And note that - aiui - C# still doesn't compare very favourably with Delphi
in these benchmarks even when using "unsafe" code (i.e. "direct" memory
access).

Frankly speaking, I am not impressed. ;-) If you use NVIDIA cuda platform to
run against gtx 280 graphics card, the performance improvement might be
increased 10x to 100 x faster. I have not done that code writing for this
test. But if someone on this dug list willing to pay me to write a c in cuda
code, I am willing to try. ;-)

 

I will say Delphi got advantage is just simply because Delphi using plain
memory mode, and most other C#, java adds some extra work load. To run
against cuda code, Delphi losing on memory access latency compare to gpu
vast memory bandwidth in the card. The more data volume size will show cuda
will be better than any cpu memory latency restricted code.

 

Have a nice day

HI all, 

Not yet Friday, but here's an interesting post re the relative speeds of
Delphi to other languages such as C#, C++, Java, and PHP.

Here's a taste... 

Delphi is fast, very fast 

Jesper Hald and others recently did a benchmark of a certain algorithm to
figure out, which was fastest. It evolved into a kind of competition to make
the fastest algorithm to solve this problem:Fill a data structure with
1,000,000 random, unsorted values from 0-100 Run through this data structure
200 times, counting a) number of values = 42 b) average for all
1,000,000*200 valuesThe benchmark was run on a new T5800 Toshiba laptop
running 32-bit Windows Vista. Nothing had been done to the Vista to make it
faster or behave in a special way.The results were interesting, and our
conclusions were:
