Around $155 users will get better latencies and voltages down to 1.5v. Taking a quick look at Newegg I see that a user can buy quite a few different 2 x 8 GB 2133 kits anywhere from $139 to $145 with similar or better latencies/voltages. Apparently (and I was not given this info before hand) the 4 x 4 GB kits with the 64 GB RAMDisk will retail at $155. Perhaps my tone was a bit too sarcastic, but I just am not seeing the value here. Better throw in another CPU and motherboard so a user can at least have 16GB of memory available as, you know, memory. Considering that the top SKU will feature 4 x 4GB DIMMS, a user only needs to buy four kits and four motherboards and processors to get a 64GB RAMDisk. Combine the two and we have AMD Radeon Memory RG2133 with 64 GB of RAMDisk. Radeon RAMDisk is not just a comic superhero, it can improve overall system performance. So yes, more memory that goes faster is better. When dealing with upwards of 16 GB of memory for a desktop computer, sacrificing half of that is really not that big a deal unless heavy duty image and video editing are required. It does exactly what it is supposed to, but of course it takes portions of memory away.
Tim covered the previous release of AMD memory pretty well, and he looked at the performance results of the free RAMDisk software that AMD bundled with the DIMMs. They will not sell these parts for a loss, and they will have buyers with the diehard AMD fans. So why is AMD doing it? Well, I guess part of it is simply brand recognition and potentially another source of income to help pad the bottom line.
It is very much a commodity market that is completely saturated with quality parts from multiple manufacturers. Let us face it AMD is not particularly doing anything new here with memory. Then they brand it! Then they throw in some software to make RAMDisks out of all that memory that you are not using.
AMD makes memory! Ok, they likely contract out memory.
