Sizing up the chip
Despite the omission of double-precision math support, Juniper's transistor count still exceeds the RV770's somewhat, as the numbers in the table to the right attest. Because, like Cypress, the Juniper GPU is manufactured using a 40-nanometer fab process, it's a much smaller chip, thoughcloser in size to the RV740 GPU in the Radeon HD 4770. As you might be gathering, that means Juniper packs a heckuva wallop for its size. We'll get into specifics on that front shortly.
Please note that the numbers in the table are somewhat approximate, since they're culled from various sources. Most notably, Nvidia has avoided divulging die sizes for its largest chips, so our GT200 and GT200b numbers are potentially off. I just Googled around for them and settled on the most widely accepted numbers. You may prefer the "spin the bottle method," which could produce more accurate results. I've not pried the cap off of a GT200/b to check them. Hence the asterisks.
Below are pictures of the various GPUs sized up, again approximately, next to a quarter for reference. As you can see, Juniper is very much a welterweight.
