Along with the Turing architecture, NVIDIA used GDDR6 memory in its graphics cards, which we later saw in the AMD Radeon RX 5000 and Radeon RX 6000 cards. In addition to the aforementioned company, Korean Samsung also has a significant share in the production of DRAM dice for graphics cards. The company has just revealed its plans for the near future when it comes to the RAM memory and VRAM for GPU systems. The novelties in the context of DRAM modules for graphics cards promise to be interesting. Samsung is currently developing GDDR6 + and GDDR7 bones. In both cases, we can count primarily on a much higher bandwidth.
Samsung revealed the first information about plans for the further development of the DRAM memory market for graphics cards. After GDDR6, the time will come for GDDR6 + and GDDR7, respectively, which will be prepared for new generations of graphics cards. They are to be distinguished, among others, by higher bandwidth.
NVIDIA GeForce RTX 3000 – Micron confirms GDDR6X memory
During the presentation of Samsung Tech Day 2021, the Korean manufacturer discussed the latest technologies that he is working on in the context of DRAM memory. Among the new products that Samsung is currently working on, it is worth mentioning the GDDR6 + and GDDR7 memory. The former is a streamlined version of the current GDDR6, which are expected to offer not only higher speeds but also improved energy efficiency. As for the maximum effective clock speed, the GDDR6 + is expected to reach 24,000 MHz (24 Gbps). For comparison, currently the fastest GDDR6X bones from Micron reach speeds of up to 21,000 MHz. Increasing the GDDR6 + clock speed will also have a positive effect on their throughput. The graphics card using a 256-bit bus will achieve a bandwidth of 768 GB / s. For 320-bit / 352-bit / 384-bit buses it will be over 1 TB / s.
SK hynix has successfully started the production of HBM3 DRAMs with a throughput of 819 GB / s per stack
The new generation bones – GDDR7, are going to be even more interesting. Samsung declares that they will achieve effective clock speeds of up to 32,000 MHz (32 Gbps). Memory with this speed and using a 256-bit bus, it will be able to achieve a bandwidth of up to 1 TB / s, For a 384-bit bus it will be 1.5 TB / s, and for a 512-bit bus – 2 TB / s. In addition, Samsung GDDR7 memory is to use the new technology of error correction in real time. The new memories are to be used in next-generation graphics cards, but it is currently hard to say whether there is a chance that they will appear, for example, in NVIDIA and AMD cards based on the Ada Lovelace and RDNA 3 architectures. the first memory supporting the DDR5 standard has recently appeared), which, according to the manufacturer, are to offer twice the speed at a minimum of 12800 Mbit / s, with the possibility of OC up to 17000 Mbit / s. However, their debut will take place in a few years, so now it is more of a song of the future.
