After the GeForce 8600 GT DDR2, there is now the case of second class Radeon HD 2000s. Here however, it doesn’t concern savings made on memory.
Commercialized Radeon HD 2400s are based on RV610 chips in A14 revision and the Radeon HD 2600 on a RV630 in A15 revision. Previous revisions posed different issues (A13 for RV610 and A14/13 for RV630). For several weeks now several sources indicate that AMD has sold previous revision chips which have fewer units and/or a non-functional UVD. This alone is enough to make us worry if we were to see these Radeon HD hybrids appear.
The normal version of the RV610, the A14.
Given the delicate nature of this subject, it was difficult to get answers from AMD. However upon insistence and after having told the manufacturer that we had the details on a batch of 10,000 older revision chips delivered to Palit and Sapphire, AMD finally answered that the A13 revision of the Radeon HD 2400 had indeed been sent out. They also indicated that if the UVD wasn’t currently functional, future drivers would activate it. The only thing is that if revision A13 UVDs don’t function in the same way as the final revision (given that a new driver is needed), we can only wonder if it will really be completely functional. On that side, AMD claims that all Radeon HD 2400s and 2600s entirely support UVD, let’s just hope this is really the case.
These cards will fortunately not be seen on the retail level and will be reserved for OEMs. In addition, Sapphire specified that these cards would be distributed on the Chinese market. The OEM market (even more in China) thus seems of a good use for GPU and graphic card manufacturers to sell anything and everything.
