SYSTEM_INFO structure
PROCESSOR_ARCHITECTURE_AMD64 stands for x64 (AMD or Intel)

I suggest that instead of reporting "AMD64" PHP_uname('m') would report "x64".

I believe it should return x86_64 - like it does on Linux:

php -r 'echo php_uname("m");'
x86_64

To change it would be a considerable BC break though, http://lxr.php.net/xref/PHP_TRUNK/ext/standard/info.c#php_get_windows_cpu has been like that for a long time.

Not sure what is the best thing to do, it would be nice if they were consistent with each other, but I don't see a good way to actually do it.

IMHO this shouldn't be changed. AMD64 is historically a synonymous for any 64-bit architecture. This is a common terminology, on Windows it's a standard keyword, on some Linux distros  (fe Gentoo) as well.

Thanks.

I'm also seeing php_uname() reporting the wrong machine information

example output from php_uname()
Windows NT ELITE800 6.2 build 9200 (Windows 8 Professional Edition) i586

vs as reported from the substring in the user agent
Windows NT 10.0; WOW64

Machine is actually Windows NT 10.0; WOW64 so it seems something isn't reporting or parsing correctly in php_uname().

I should mention the PHP version is 5.5.30
