Need quick way to identify A5/A4 devices - iphone

Question

I need a quick way to identify A5/A4 based iOS 7 devices (iPhone 4S and below). I can not rely on UIScreen bounds as iPod touch 5g also has same A5 processor as iPhone 4S. I need it to determine the processing capability.

You can distinguish devices with this code
+ (NSString *) platform
{
size_t size;
sysctlbyname("hw.machine", NULL, &size, NULL, 0);
char *machine = malloc(size);
sysctlbyname("hw.machine", machine, &size, NULL, 0);
NSString *platform = [NSString stringWithUTF8String:machine];
free(machine);
return platform;
}
+ (NSString *) platformString
{
NSString *platform = [self platform];
if ([platform isEqualToString:#"iPhone1,1"]) return #"iPhone 1G";
if ([platform isEqualToString:#"iPhone1,2"]) return #"iPhone 3G";
if ([platform isEqualToString:#"iPhone2,1"]) return #"iPhone 3GS";
if ([platform isEqualToString:#"iPhone3,1"]) return #"iPhone 4";
if ([platform isEqualToString:#"iPhone3,3"]) return #"Verizon iPhone 4";
if ([platform isEqualToString:#"iPhone4,1"]) return #"iPhone 4S";
