New ePSXe for x64?

[MoJo]

As everyone's known, AMD has release ADM Opteron 64 for Server and will release AMD 64 by the end of 2003. 64 bit is really powerful. AMD said there's so much improvement in perfomance and graphics. Is ePSXe team and plugins going to port ePSXe 32 bit to 64 bit? And if it suceed, are there any major changes in graphic or performance or compatiblity? And I think emulator running on x64 bit will be easier to code because some consoles use 64 bit processor such as Nintento 64. Maybe AMD will create a revolution in emulation of XBOX, PS2 or DreamCast and N64.

I'm no Developer but porting apps from 32 to 64biits should be just a matter of recompiling.
Any way i don't think 64bits will help emulation that much but then again what do i know

[Galway no Sora]

It's depend on the OS, if supported then the "new" ePSXe 64bit will work on it. But I don't think that the emu author will release the 64bit version soon enough.

BTW, if it run at 64bit it will increase the performance significanly. Again, if the OS support it

[Gamer1]

there is no point porting the emu to 64bits. i severly doubt we could see performance increases to epsxe.

xbox... nah... xbox uses a 32bit proc.

Nah remember, PS2 processor is 128bit. Our desktop computer is only 32bit altough have faster speed.

Well, the point is that PC and consoles use completely different procesor architectures. While consoles (xcept the XBoX) mainly use RISC-processors ("Cheaper, Smaller, Faster"), PCs (including the XBoX) still use x86-processors (believe it, or not: a P4 uses the same technology as the old 186 CPU!).

Owing to that difference 64-Bit technology won't help emulation very much, because you'll still have to emulate the CPU of a console.

I'm not sure what x64 can do better than x32? But I remembered 2 months ago, on a review about SuSE running on AMD x64 (Demo Chip) with GF 2 MX achieve higher graphic quality than that of use x32 processor. So I reckon it's obviously improve the quality gpu of emulation.

[F-3582]

Well, I just think that x64 can operate faster than x32.

X64 processors will operate faster than X32 processors. The current AMD X64 processors are, as has been said, the Opertons and they are out now. But they are only designed for servers and are extremely expensive. The X64 processors for the home users are the Hammer series and they are due out in the fall of 2003. Right now the cureent line of AMD processors, the Throughbreds and the newer Bartons are doing an excellent job of filling the gap until the Hammers arrive. Be warned though, when the Hammers arrive they are going to be quite expensive at first and you will, most likely, need a new motherboard. One that will support a 64bit processor.
As for the Hammers improving the speed of console emulation, I seriously doubt it. You see, the consoles CPU is being emulated and all the instructions for it are being emulated, so the emulated console will run at the proper speed of the original. Regardless of whether or not you are using a Throughbred, Barton, or Hammer CPU in your PC.
Lastly, yes, all modern CPUS, 32 bit or 64 bit, Intel 2.8 ghz or AMD Barton 3200 are based on the original X86 processor technology developed in the late 1980s and early 1990s.

Well, I think a 64 bit processor would definately improve emulation speed for systems like the n64 cause it would allow the emulation of registers without too much slow memory access. For the psx though, it seems pointless since the psx cpu is only 32 bits to start out with. And besides that the major bottleneck is psx emulation these days seems to be lack of proper framebuffer support in pc gfx cards. Actually, I think graphics emulation is the problem in pretty much all next gen systems, so I'll wait until pc gfx cards start supporting console-like features to get exited.

I think the only benefit the emulation scene will have from the 64 processors its for emus of next generation consoles like the ps2. Right now we have the better a psx game can look. The only thing that could improve its speed but even a p4 with a radeon 9000 and 512 of ddr ram can run ff9 with everything maxed out.

if they ever make a x128 architecture then u know the games of dreamcast and ps2 and gamecube would operate faster even if u have your same processor because if the pc is x32 or x64 it takes more power to emulate the game. i think 2005 we will see x128 probably in the fall.

[Kane]

I doubt it. It's taken over 10 years for them to switch from 32-bit, and they still ain't doing it in 'full force'. I don't think we'll see a 128-bit CPU for a long time yet.

[stevehabs]

point being if they ever do come out tho emulation will see its glory days

[Kane]

No. Emulation is in it's 'glory days' the moment the first game is played on a new emu. Over time people forget how cool it was to get that working in the first place. Look at SNES emulation now. When the emu for that first appeared with sound everyone was like 'WOW', but now it's more indifference. PSX emulation is losing its wow factor for many now as well.
A 128-bit CPU does not automaticaly make the emulation of a 128-bit machine easy.

[n_w95482]

By the time 128 bit pc cpu's come out consoles probably will be at 256 512 or 1024 bit anyways. Consoles probably will be ahead of pc's bit wise for a long time, but it doesn't matter. The console will be emulated eventually, no matter how powerful it is. But as lord kane said, having a 128 bit cpu will not necessarily make emulation of a 128 bit console easier. You have to take in account the architecture of the ENTIRE console (cpu, gpu, memory, i/o, etc.). That's what makes emulation of ps2 so difficult: there's a lot of things to be emulated, such as the cpu (with 2 vector processors that are supposedly very hard to emulate) gpu, memory, cd/dvdrom drive, and the i/o processor that is used for i/o (that's why its named that) as well as emulating ps1 (that part probably will be ignored by ps2 emulators). I don't know everything about emulation (especially ps2 emulation) so I am probably wrong on some of these points.

[stevehabs]

well by years end cxbx and pcsx2 should both have some games working
