All times are CPU times, not elapsed times.

Haswell Core i5-4670K (stock speeds), Win 7, all 4 cores plus AP27 running on the GPU: about 4600 to 4800 seconds per task. (Remember, each base is actually a separate sieve and they're not exactly the same length.)

Same system, but 32 bit linux in a VM: 11643 CPU seconds. We don't talk about it much these days because there are so few 32 bit systems around, but sieves take a HUGE hit when you're running 32 bits. The difference in speed is due to the 32 bit app being that much slower. It's not because of the VM.

32 bit Sempron, Windows XP: 41552. No, that's not a typo. But it's sitting in my electrically heated basement, so as long as it's cool enough to need the heat, the electricity is essentially free down there. :)

Interesting side note: The one task completed so far on the Sempron is still waiting for its wingman on an i7-6700K!

Pentium E2180 2.0ghz: min of 11,220, max 11,528. The average of 9 tasks seems about 11,409s per task.

AMD A6-3500 (2556mhz): min of 14,760, max 15,467. The average of 4 tasks is 15,171s per task. Quite surprised, I must say, I was expecting the AMD system to be faster than the Intel one. Guess it's not...

Same system, but 32 bit linux in a VM: 11643 CPU seconds. We don't talk about it much these days because there are so few 32 bit systems around, but sieves take a HUGE hit when you're running 32 bits. The difference in speed is due to the 32 bit app being that much slower. It's not because of the VM.

I noticed this as well with the dramatic difference due to the operating system (32- vs 64-bit). I will sit down and reformat the disk with a 64-bit OS.

Interesting side note: The one task completed so far on the Sempron is still waiting for its wingman on an i7-6700K!

I had to check since I am also involved with the first generated work unit for this project. I requested three days' worth of work since I am looking to go as far as Gold and then back to TRP Sieve. I am processing at a pace of 100 units per day on the i7 6700k and I will certainly get to it over the next 48 hrs either way.

E5472 3ghz 7080-7250 (6/8 cores)
E5462 2.8ghz 7633-7757 (6/8 unless I am running something contending for cpu time...)
P8600 2.4ghz 9401-9554 (2/2)
Q9550 2.83ghz 7366-7646 (3/4)

Those old CPUs are good for something after all.

Given the suspension of ESP Sieve and the uncertain status of TRP Sieve, GCW Sieve is a godsend. My two old(er) Dell laptops with the duo core P9600 chip (2.67 GHz) are putting out 16k+ per day between them!

i7-4790 * 3.6GHz, HT on, 4 units, DDR3 1600 dual channel, Win 7 Pro
~5000s/WU (4700-5200 so far)

Will report on my old Athlon II 635 tomorrow when it's done its current TRP LLR tasks and gets some of these GCW SV tasks.


First result is in.

Athlon II X4 635 @ 2.9GHz, no HT support, 3 units, DDR3 1333 dual channel, Win 7 Pro 64bit
12,043s/WU

Not bad for a 6 year old CPU compared to what others are getting on much newer and higher end hardware.

i5-4590T CPU @ 2.00GHz (Haswell) Typically under 6300 seconds (105 minutes) per GCW Sieve WU with a mix of TRP Sieve and GCW Sieve, all 4 cores crunching.

This thing is unbelievably fast. It's a stock HP ProDesk 600 G1 small form factor PC, except that I took out the 500 GB hard drive with Windows 7 Pro preinstalled as soon as I unpacked it, put in a SSD and installed Linux. It hardly makes any noise and it's not very hot. It's consistently my fastest performer on every single PrimeGrid task. There must be dual rank memory in the thing. I have no other explanation for its surprising performance.

Any benchmarks for an Intel Core i3-3240 (3.4GHz) processor would be very much appreciated.

Averaging the last 20 valid results:

i7-4770K@4.2 6/8 Tasks (w/ GFN and WUProp running) Win10 - 5598sec Run Time
i5-3470 stock 3/4 Tasks (w/ GFN and WUProp running) Win7 - 5897sec Run Time
i7-720QM stock 6/8 Tasks (w/ PPS SV and WUProp running) Win7 - 20693sec Run Time

Somebody tell me how the stock i5 (3.2GHz) is running these things 95% as fast as the overclocked i7. I am perplexed.

Hyper Threading. It increases the individual time it takes for each task to complete, though it makes up for it by doing more tasks at once.

Didn't realize it was that big of a hit in performance for sieving tasks. I know that (compared to itself) it will run faster if I turn HT off and run 3/4 tasks.

But given that I'm not doing a full 8/8 tasks, a 23% faster clock (the i5 is actually running mid turbo @ 3.4) and slightly faster RAM (1866 vs 16oo), I really expected the i7 to be much faster on the individual tasks not just the overall throughput.

The main gripe of course is that this is work computer (off the shelf Lenovo) vs home computer (custom build, lovingly hand assembled from specifically chosen component parts) and the home computer should be absolutely and unequivocally crushing the work computer.

I could swear I remember reading at some point that the amount of cache played a factor with sieving...

My ancient C2Q has 12Mb of total cache and is now taking 7062 seconds per task on average with all 4 cores active. My I7-3770s have 8Mb. I'm running flat out with those, 8 threads each, and the best I can get is 8996 and 9084 seconds (average of last 20 tasks), Win7 vs. Win10 respectively. The Windows 10 has slightly faster memory as well.

I'll disable HT on the Windows 10 system once the current batch finishes and see what happens.

I can verify that the 64 bit application is much faster than the 32 bit one. I have a 2006 era Core 2 Duo system that I fire up for challenges. The installed OS is 32 bit Win-XP, but after reading through this thread I popped in a 64 bit linux live CD. It runs pretty much twice as fast. I imagine part of it is the upgrade to a modern linux kernel from the older-than-dirt Win-XP, but most of it is the change from 32 to 64 bits.

16 GCW-Sieve tasks on 32-bit WinXP averaged about 13663 seconds each. Computer/Tasks

16 recent GCW-Sieve tasks on 64-bit Xubuntu averaged about 6522 seconds each. Computer/Tasks

Normally it doesn't contribute a whole lot to my total challenge scores, but it's holding its own this time - within spitting distance of the i5 Sandy Bridge and the OC'd FX 8320.

I can verify that the 64 bit application is much faster than the 32 bit one.

I have observed something similar:

Dell with P9600 2.67 GHz (Win 7 Pro 64-bit) @ 105.0 min/unit
Dell with P9600 2.67 GHz (Win Vista Bus 32-bit) @ 193.6 min/unit

I have some warez which will only run on 32-bit OS and which explains why I have not migrated over to 64-bit.

I imagine part of it is the upgrade to a modern linux kernel from the older-than-dirt Win-XP, but most of it is the change from 32 to 64 bits.


Actually, the OS has almost no impact on the speed. It's pretty much all the switch from 32 bits to 64 bits. Crunching programs essentially never make calls to the OS, so the OS has no impact on the speed. (If the OS tends to run lots of tasks in the background, like Windows does, that DOES have an impact, of course. But that's the background tasks, not the OS, that are slowing you down.)

Back then, I had a Core2 Quad running 32 bit Vista. It's possible to run a 64 bit VM on a 32 bit host OS if the CPU has the VT-X feature, so I was able to run 64 bit Debian in a VM on that 32 bit system. I would do that whenever we had a CPU Sieve challenge.

That computer has since died and been replaced, but my other computer, still running, is running 32 bit XP, and can't do that -- because it's really a 32 bit CPU. :)
