Meet The Whole Family!

ATI has been hammering away at NVIDIA?s firm grasp on the hearts and minds of gamers, multimedia enthusiasts, corporate users and laptop owners.  Up until now, they have done so with individual product announcements, like the RADEON 9700 Pro, RADEON 9000 Pro, and so on.  Each card effectively delivered a well-aimed blow to NVIDIA?s comprehensive lineup, currently consisting of the GeForce4 Ti and MX families.  With the 9000 and 8500 cards covering the mainstream market, ATI is poised to further its cause in the mid and high-end 3D arenas, filling the gap between the RADEON 9700 Pro and the RADEON 9000.

As we've already seen, the R300 Visual Processing Unit is an ace for ATI; a hot commodity.  It?s the first consumer level graphics engine with eight rendering pipelines and 128-bit per pixel floating point color support.  The chip employs four geometry engines to process up to 325 million polygons per second, when clocked at 325MHz .  In essence, the R300 is the first chip that adheres to Microsoft?s DirectX 9 specification, putting it in direct competition with NVIDIA's upcoming NV30.  NVIDIA?s next-generation part isn?t quite ready yet, though.  And despite rumors that have been circulating about a launch during this year?s Comdex, it is doubtful hardware based on the anticipated competitor will be ready at that time.  So, while NVIDIA puts the finishing touches on NV30, ATI is readying an entire family of cards designed to leverage the power of its R300 processor across several price points.

The RADEON 9700 Family
GeForce4 Ti 4600 Killer

Vital Stats:

RADEON 9700 Pro: 325/620MHz core/memory, R300 core with eight parallel rendering pipelines, 128MB of DDR memory on a 256-bit data path (19.8GB/s of bandwidth)

RADEON 9500: 275/540MHz, R300 core with eight parallel rendering pipelines, 128MB of DDR memory on a 256-bit data path (17.3GB/s of bandwidth)

We're going to go out on a limb here, and assume that the RADEON 9700 Pro needs no introduction.  If you would like to refresh your memory, check out our review, however, the important fact is that ATI?s RADEON 9700 Pro is currently able to outperform any competing 3D card.  On the 9700 Pro, the R300 core runs at 325MHz and is complimented by a 256-bit memory bus clocked at 310MHz DDR, or effectively 620MHz. 

Not all of the cores ATI receives back from the fabrication plant are capable of 325MHz, though.  Many function perfectly, yet are not as tolerant of high frequencies.  NVIDIA has used this concept of yield to build the GeForce4 Ti family.  The processors are sorted ? the best become GeForce4 Ti 4600 cards, others, reliable at 275MHz become Ti 4400?s and the rest are used for Ti 4200 cards.  Of course, this doesn?t mean a GeForce4 Ti 4200 card can?t be overclocked to run at the same frequency as a 4400.

Using a similar technique, ATI is introducing the "non-Pro" RADEON 9700 to compliment the more expensive Pro.  Both 9700 cards will feature the same R300 VPU with eight rendering pipelines and a similar 256-bit DDR memory bus (with 128MB of memory).  The distinguishing characteristic of the RADEON 9700 will be its operating frequency: 275MHz core and 270MHz DDR (540MHz effective) memory.  Then there is the $299 price tag, which should put the card in the same league as the GeForce4 Ti 4600 with regard to both price and performance.  Further, ATI claims the RADEON 9700 will be available as soon as this month.
