Although the RTX 50 series debuts newer, faster GDDR7 memory, almost all sources indicate that Nvidia will stick with standard 16Gb (or 2GB) modules for these GPUs. However, according to rumors from a famous leaker Golden Pig Upgrade PackageNvidia may equip the RTX 5090 phone with a 24Gb (or 3GB) memory module, bringing the total video memory to 24GB.
Nvidia’s RTX 50 series GPU, codenamed “Blackwell”, will be the first consumer product to use GDDR7 memory. This new memory offers several advantages over GDDR6 and GDDR6X, including higher speeds and higher density. Samsung is developing 42.5 Gbps GDDR7 The 24Gb (3GB) form factor module is expected to be in mass production soon. A word on the street The RTX 50 mobile and desktop GPUs may be released simultaneously next week.
RTX 50 product stack RTX 5090, RTX 5080and RTX 5070 It is expected to debut with lower-density 16Gb (2GB) GDDR7 memory modules. If this rumor holds true (we’ll probably find out next week), then it begs the question: Why is Nvidia using a denser 24Gb module specifically for the RTX 5090 mobile device? Ransomware attack blue sky Many months ago, a successor to the RTX 4090 phone with 16GB of RAM was proposed. Although the report dates back to June, we recommend you take this leak with a grain of salt.
The supply of denser GDDR7 modules is likely to be limited, a situation that is expected to improve as the technology matures. exist Global Technology Conference 2024Samsung and SK Hynix announced that the first wave of GDDR7 memory will center on 16Gb capacity, with plans to launch 24Gb models later.
Echoing its predecessor, the mobile version of the RTX 5090 may feature the GB203 GPU chip, which is also rumored to be used in the desktop version of the RTX 5080. Leaker reports that Nvidia is using higher capacity modules to overcome the limitations of the 256-bit bus. This shows GB 203 Physically limited to 256-bit interface; supports 8 16GB modules (16Gb/2GB modules) or 24GB memory (24Gb/3GB modules).
A growing concern with desktop and notebook GPUs is limited memory capacity. The VRAM capacity in AD103 and GA103 GPUs is limited by the 256-bit interface. Therefore, even the professional workstation GPUs, namely the RTX A5500 Mobile (GA103) and RTX 5000 Mobile Ada (AD103), only offer 16GB of memory.
The RTX 5090 mobile device is rumored to come with 24GB of memory, and its workstation version is expected to have the same performance. Furthermore, if Nvidia wanted to, budget Blackwell GPUs like the RTX 5060 could easily come with 12GB of VRAM, even on a cramped 128-bit memory interface. Just for thought, but in theory, a 48GB RTX 5090 is entirely possible; Nvidia isn’t saying it would release such a GPU because it might cannibalize its data center revenue.
