Samsung innovates GDDR6W standard, provides better performance in less space
Today, Samsung announced the “GDDR6W” video memory developed on FOWLP technology that significantly improves bandwidth and capacity. Samsung believes, high-performance, large-capacity, and high-bandwidth memory solutions are helping the virtual realm get closer to reality.
In order to meet this growing market demand, the South Korean tech giant has developed GDDR6W (x64), the industry’s first next-generation graphics DRAM technology. Since its initial release, Samsung GDDR6 tech has witnessed significant improvements.

In July 2021, the company announced that it has developed a 24 Gbps GDDR6 model. However, the new GDDR6W doubles bandwidth (performance) and capacity while maintaining the same size as the GDDR6.

As you can see in the image below, the graphics DRAM capacity has increased from 16Gb to 32Gb as twice chips can be carried in the same size package. Adding to this, the bandwidth and I/O number have increased from 32 to 64.
FOWLP technology mounts memory chips directly on silicon wafers rather than PCBs. In the process, the company applied RDL technology to achieve finer wiring patterns.
Since no PCB is included in the package, the thickness is reduced and heat dissipation is improved. With a height of 0.7mm, the FOWLP-based GDDR6W is 36% thinner than the previous 1.1mm package.
However, the chip is multilayered, it still offers the same thermal traits and performance as the GDDR6, but, the FOWLP-based GDDR6W can double the bandwidth due to doubling the I/O per package.
When it comes to performance, the GDDR6W can generate 1.4TB/s bandwidth at 512 system-level I/Os and a transfer rate of 22Gpbs per pin. Since Samsung completed the JEDEC standardization of GDDR6W products in the second quarter of this year, the GDDR6W could also debut with future Galaxy Book laptops.

Samsung’s executive chairman Jay Y. Lee (Lee Jae-yong in Korean) topped the Forbes 2024 Richest Korean list for the first time. On April 17, Forbes revealed that the Samsung boss is the richest in South Korea, with his assets increasing by $3.5 billion, bringing his total net worth to $11.5 billion.
Thanks to a rise in Samsung’s stocks, Samsung’s Lee jumped to the top of the Forbes 2024 Richest Korean list. Notably, the company’s stocks significantly hiked after the revelation that it’s developing high-bandwidth memory chips used in AI computing for NVIDIA.
Forbes 2023 Richest Korean, Kim Byung-ju, slipped to second this year with assets worth $9.7 billion. The third place went to Seo Jung-jin, honorary chairman of Celltrion, with assets of $7.5 billion.
Cho Jung-ho, chairman of Meritz Financial Group, ranked fourth with $6.2 billion, and Chung Mong-koo, honorary chairman of Hyundai Motor Group, was fifth with $4.6 billion.

Samsung established an AI chip design-dedicated Advanced Processor Lab in Silicon Valley, US. Formerly known as the Advanced Institute of Technology, Samsung’s SAIT is said to have formed the new Lab to strengthen its AI chip R&D in the US.
BusinessKorea reports that the new Samsung Advanced Processor Lab to focus on developing next-gen AI semiconductor design assets in the US. The assets are said to be focused on the RISC-V area, which serves as a foundational design asset for semiconductor chip design.
Samsung’s initiative with RISC-V is interpreted as a move towards technological independence. Therefore, the company is expanding its R&D organization in Silicon Valley, aiming to enhance design capabilities to disrupt the market currently dominated by NVIDIA.
Amid the booming AI era, the market of advanced semiconductors is also expanding. Samsung has completed the development of its Mach-1 AI semiconductor and supplied prototypes to global firms including Korea’s Naver. The company has also started the development of Mach-2.
Under the CHIPS Act, Samsung received huge subsidies to boost investment in the US. It’s worth noting that the Biden govt awarded a 12% subsidy of Samsung’s total investment, which is significantly higher than Intel and TSMC’s subsidy.

Samsung’s first 3nm Exynos 2500 chip could outpace Snapdragon 8 Gen 4 in power efficiency. Both chipsets will power the next-gen Galaxy flagships, scheduled for an early 2025 launch. Recent input suggests that Exynos is returning as a tough rival to Snapdragon.
The Exynos 2500 will be made on Samsung’s 2nd-gen 3nm process technology. The S24’s Exynos 2400 chipset impressed the industry with significant improvements over its predecessor. The company appears to be leveling up the game next year.
Thanks to the cutting-edge process node, Samsung’s next Exynos could finally surpass its Snapdragon counterpart in power efficiency. The company may utilize its advanced FOWLP in the Exynos 2500 to make it run at higher clock speeds at the same power consumption level.
Qualcomm is facing power efficiency concerns with its recent Snapdragon chips. Due to reduced efficiency, phone makers are forced to bring up to 5000mAh battery. Samsung apparently seized this opportunity to bring back its in-house Exynos back to the contest.
