Micron to launch GDDR7 in 2024, AMD RX 8000 series may be launched first

【Lansheng Technology Information】Recently, Micron announced its financial report for the third quarter of fiscal year 2023. In the earnings conference call, Micron President and CEO Sanjay Mehrotra confirmed that Micron will choose to launch new GDDR7 memory products on the 1ß node in the next year. However, no details were shared, such as the specific rate of GDDR7.

The current mainstream video memory specification is GDDR6. For example, the highest frequency of AMD’s RX 7900 series has reached 20GHz, while Nvidia’s mid-to-high-end cards have popularized GDDR6X, and the frequency of RTX 4080 has reached 22.4GHz. GDDR7 will inevitably greatly increase the frequency, but how much can it increase?

According to the information disclosed by Cadence Design Systems, GDDR7 memory will use the new PAM3 encoding, which uses three-level pulse modulation, which greatly increases the data rate and can transmit 1.5 bits of data per cycle. The current mainstream GDDR6 uses PAM2 signal encoding technology. Only 1 bit of data transfer is provided per cycle.

At the same time, according to Samsung's news, the GDDR7 rate it plans to launch can reach 36Gbps. If calculated based on this, it can have a maximum bandwidth of 1728GB/s under the premise of 36Gbps 384bit. For 128bit mainstream graphics cards, the memory bandwidth can also reach 576GB/s. , based on Nvidia's flagship product RTX 4090, the bandwidth of 1728GB/s is about 70% higher, so overall, GDDR7 is at least 50% faster than the current one.

And just in March this year, EDA giant Cadence has launched the first GDDR7 VIP verification solution, which supports the PAM3 signal mechanism and provides three solutions: binary bus, strength modeling, and real number modeling. GDDR7 already has the basis for listing . If Micron decides to mass-produce GDDR7 memory in the first half of next year, then maybe we can see the launch of a new generation of graphics cards in the second half of next year.

Judging from the current news, the Nvidia RTX 50 series will have to wait until 2025, and according to AMD’s official roadmap, it will launch the next-generation RDNA4 architecture before 2024, which will be listed under the name of the RX 8000 series, so maybe AMD will Will become the first manufacturer to try a new generation of video memory.
