I was just wondering what will we (gamers) gain from an AMD Athlon 64?

Another thing to dream of spending our upgrading money on. :lol:

But since there are no 64-bit games, how will the AMD Athlon 64 improve gaming?

UT2003 or something will be a 64bit game.

What about Doom III?

64-bit OS, so 64-bit drivers, so hardware calls will be faster.

Or something like that. :D

UT2003 took about a week to convert to 64 bit..
so when Athlon64 is out there is no doubt
in my mind that new games will ship with support for
the new 64bit features..

Also Sweeney at Epic ranted on
how great this was that devs can build cheap 64bit
servers with opteron in contrast to the VERY pricy
Itanium options.
http://arstechnica.com/cpu/03q1/x86-64/x86-64-5.html

And add to this that MS is working on "anvil" a
64 bit desktop version of XP for the Athlon64.
Anvil, hammer, get it?

Also Counterstrike linux server is Opteron ready
now, and shows a 30% increase.
www.counter-strike.net

From what I understand the move to 64bit wont really
yield that much performance increase, but the improved
arcitecture will, more faster cache mem, integrated
memory controllers and SSE and SSE2 support among
others..

on the topic of 64-bit computing and gaming.

UT2003: http://www.evilavatar.com/redirected.asp?fromurl=http%3A//www.evilavatar.com/EA/Interviews/Hardware/M42050/

Evil Avatar: Can you give me any idea what kind of a performance increase people might see running the 64-bit version?

Tim Sweeney: In pure CPU performance, Athlon64 is about 15% faster than previous Athlon's of identical clock rate for 32-bit apps, and 30% for 64-bit apps, because it exposes double the number of CPU registers, enabling the compiler to generate more efficient code. As for UT2003 performance, we haven't benchmarked yet but expect it to be faster though less than 30% because the GPU is as significant a factor as CPU.

Doom3: http://www.nvnews.net/vbulletin/showthread.php?s=&threadid=4578How will the next generation of 64bit CPUs affect Doom 3
64 bit is not going to speed up Doom 3. In fact there may actually be a minor slowdown since the pointer references are all in 32 bit, which will mean a hit to memory bandwidth which is the real gating problem.

Even without 64-bit, the Athlon 64 already has a nice lead over XP and p4 in games, even with the engineering sample it looks extremely probable for it to be the fastest gaming proc once it starts gaining speed and is matured. AMD has already stated that the opteron is a kickass gaming proc, but they took off agp slots form mobos because they didnt want it associating with gamers, so this should give you a hint to gaming performance on the A64

The AMD Athlon XP and Intel Pentium 4 outperformed it in games.

And how old was that preview? The inquirer also did a test on the A64 with games, it got 7k in 3dmark and disappointing scores. Then they posted a followup regarding an error with the chipset and agp, in that article it scored 15k in 3dmark, just like how it scored in the xbit preview

I know theyre not full fledged previews, but still shows the problem with early tests with opterons

Thanks.

But check this quote I got from there: This setup easily passes the 15000 line and gets very close to 16000 in 1024x768. That is a score that should be in the range of new P4s.

Inquirer = yuck

let's get some x-bit lab's loving in :p

fast in gaming benchmarks, but other things are not so good.

except, xbitlabs is probably the worst written stuff ever... hell, I wouldn't trust it farther than I can throw it. ;)

When is the AMD Athlon 64 meant to be released?

04-21-03, 04:52 PM
September. And i think the new intel chip comments means the 800mhz fsb p4s, since i think that article was written b4 that

I think its scoring low in some tests cause of the
relativly low clock..
Some apps dont benefit as much from cachemem and
such as they do from pure Clockrate...
As seen in some bartons review the Xp2800+ outperforms
the xp3000+ in apps like 3dsmax cause its more sensitive
to clockrates...
http://www.anandtech.com/cpu/showdoc.html?i=1783&p=21

So hopefully it scales well to high clockrates..

yes, and this will continue to be a problem unless AMD changed the way they calculate the Performance Ratings.

The Baron

Ah, but do you think the Athlon64 will be released at a paltry 1.6Ghz? I think we'll see AT LEAST 2Ghz by September, and maybe up to 2.4. 2.4 is unlikely except on a $600 chip, but it will be faster than 1.6.

Gotta give early adopters a reason to adopt.. ;)

of course not.

but if there are any Bartons that have the same PR as the Athlon64s being launched then we will see the same problem.

obivously the Athlon64 will probably have some flavors with a higher PR rating than any Barton and will continue to scale higher, as it is AMD's future platform. but I wouldn't be surprised if the lowest PR Athlon64 had around the same rating as the highest PR Barton.

Arent they also coming out with Mobile ports of A64?
