Windows 7: x86 vs x64 = which is faster

29 Jul 2009   #1

Windows 7 Ultimate x64
x86 vs x64 = which is faster

All things being equal i.e. RAM (3 GB), Processor, Graphics Card, etc.

Which OS would be faster ? Windows 7 RC x86 or Windows 7 RC x64 ?

XP / Windows 7 Pro RTM

You're probably just going to get opinion unless you run some benchmarks yourself.

Faster at what? Some applications, or application types, benefit greatly; others do not. Few modern applications suffer. The answer also varies by platform, meaning that not all hardware is equal. This is where benchmarking serves you.

Conceptually, 64 bit is substantially faster when properly configured and implemented. Think XBox 360 vs. Super Nintendo. Or something like that.

Windows 7 7264x64(main), 7260x86(secendary), XP SP3 Triple Boot

tests have been performed on this, for vista this is one of them , on PCMark test, 64-bit seems to have a small advantage, but on 3D Modeling and rendering test/Media Editing and encoding there is little difference. also not much difference in first person shooters RTS games.. in general there is benifit but it's still small at this stage, maybe in the future as applications start to be writen spesificly for 64-bit we will see some more improvements..

can't find any windows 7 tests yet, try googling and see if you get lucky!

Windows® 8 Pro (64-bit)

Speed depends more on the hardware. Even If you run windows 98 or 2000 on Core2Duo processor and 2 GB RAM, it will run much faster than imagined. Hence if you go for Windows 7 64bit, make sure you have correct hardware configuration or else it may run even slower than 32bit.

Windows 7 Ultimate x64

Hmmm ... Interesting.

Upgrading from Windows XP 32-bit to Windows 7 RC 64-Bit has madea significant difference for our design team in Solidworks.

The article indicated minor differences in Vista 32 to 64. Maybe when all apps are native 64 and well-coded (i.e. debugged and optimized) will we see true advantages.

64 bit wins.

Windows 7 7600 OEM

Sadly, I reverted back to x86, I didn't see ANY speed improvement, in fact, in some work, it was much slower, also of course, it took many hours of searching to gain the appropriate drivers for the hardware... no, to me, x86 "feels" more comfortable

Windows 7 Ultimate x64 ®™

Since putting it on, and running it for a month or two, x64 is "better", imo, which in turn makes it a little quicker. It has crossed my mind once or twice to revert back to x86 just because of a few tiny annoyances, but the positives for me far outweigh the negatives, and it would be like taking a step backwards.

Windows 7 Ultimate 64-Bit / Ubuntu 10.04

64-Bit is theoretically better, but it greatly depends on the applications in question, as well as the systems hardware. With the proper hardware and compatible software 64-Bit wins every time.

Going for a faster one
Hi, I’m bidding for a Dell OptiPlex 780 Small PC -Core2Duo E8400 3GHz 4GB DDR3 500GB HDD Win 7 Pro OS because it faster than my present Dell OptiPlex 520 Pentium D 2.8 GHz Win 7 X 64 Home Premium. So far I don’t know if this prospective PC is a 32 or 64bit.

USB 3.0 is faster than USB 2.0, but by how much really?
I'm a bit uncertain by just how much faster USB 3.0 is over USB 2.0. I've read a few articles where it was stated that on paper 3.0 is 10x faster than 2.0, but would never be achieved in the the real world. The "real world" improvement would be more like 3x. Now, I'm sure this is making...
