Samsung has divulged some updates on its next generation memory products—including GDDR7 memory—at its annual in San Jose. Alongside GDDR7, Samsung announced its Shinebolt HBM3E memory, which is being developed for upcoming AI and compute GPUs.

GDDR7 memory has for some time. It's set to appear in next generation and graphics cards. Samsung didn't disclose too many details, but one of the most interesting little nuggets was the reveal of a target of 50% less stand-by power. That'll help to reduce overall idle power consumption, and hopefully lower it for multi-monitor setups and video playback too.

GDDR7 memory is set to operate at 1.2V compared to the 1.35v operating voltage of GDDR6 and GDDR6X. Assuming we see high speeds of up to 32Gbps as predicted, a total bandwidth of 1TB/s is possible over a 256-bit bus. In the case of a 384-bit bus, that bandwidth would increase by a further 50%.

Samsung previously disclosed that its GDDR7 memory will utilize PAM3 (pulse-amplitude modulation) signaling as opposed to GDDR6X's PAM4. While PAM4 is better suited to higher frequencies, PAM3 is easier to implement, making it a better option for affordable consumer graphics cards. That partly explains why we've never seen affordable GDDR6X cards, even though faster memory would be beneficial when considering the relatively thin memory buses of current generation mid-range GPUs.

PAM3 delivers lower average bit-error rates, but H25 given the higher inherent performance offered by GDDR7, PAM4 is seen as the preferable option for now. Of course, that leaves the door open to a future GDDR7X standard. Is that something Micron might have up its sleeve? We'll have to wait and see. A hypothetical Ti with a 512-bit bus and GDDR7X would result in a bandwidth rating of above 2TB/s. That sounds tasty indeed, though the price of such a card would be excessive, to put it mildly.

Given where we are on the current release cycle, GDDR7 equipped cards are surely a year away at best. I'd expect h25 com สล็อต​ it to be restricted to high end cards. Next gen entry level cards are very likely to stick with GDDR6, at least until manufacturing really ramps up and it becomes cost effective enough to consider.

Samsung also talked about its next generation HBM3E memory. While we'd love HBM3E memory to be included in gaming graphics cards, its expense and complexity rules it out. Samsung says its Shinebolt memory can hit up to 9.8Gb/s per pin which would give a single HBM3E stack 1.225GB/s of bandwidth. That's much higher than the 819Gb/s offered by HBM3.

If you add multiple stacks, those numbers skyrocket. According to numbers sourced from our sister site , a flagship GPU could theoretically contain 216GB of memory with an astonishing 7.35TB/s of bandwidth. A reference RTX 4090 delivers a hardly sluggish 1,008GB/s in comparison.

Samsung has not h25 com เข้าสู่ระบบ​ said if it is mass producing GDDR7 yet, which isn't surprising given there's at least a year to go before GDDR7 cards are launched. But it is good to see that it's talking freely about it at this stage, which points towards a mature standard that's readily able to hit the market in volume when next generation cards do arrive.
