Explore the performance of Samsung’s latest GDDR7 (16Gb/32Gb/64Gb) DRAM chip series. It delivers exceptional data transfer speed and capacity, ideal for high-performance computing and graphics processing.
Specifications and Performance Features by Capacity
16Gb Samsung GDDR7 DRAM IC
Ultra-High Transfer Rate
The data transfer rate per pin can reach 18Gbps, a 50% increase compared to the previous-generation GDDR6. A single chip with a 32-bit I/O interface can transmit 72GB of data per second, and a memory module built with a dual-chip combination can achieve a bandwidth of 144GB/s. This enables fast loading of high-definition textures and dynamic lighting data for 2K resolution games, avoiding frame stuttering.
Low-Power Optimization
Built on Samsung’s advanced 12nm process technology, it features a typical operating voltage reduced to 1.2V (0.1V lower than GDDR6) and a 20% reduction in standby power consumption. When applied in mid-range gaming laptops, it effectively reduces graphics card heat generation and extends device battery life.
Stable Compatibility
It supports the JEDEC universal GDDR7 standard and is compatible with mainstream graphics card controller chips. Adopting a 78-ball FBGA package with the same size as the previous generation, it allows graphics card manufacturers to quickly complete hardware adaptation and shorten product development cycles.
24Gb Samsung GDDR7 DRAM IC
High-Capacity & Performance Balance
A single 24Gb chip can provide 3GB of memory capacity. With eight chips combined, a 24GB VRAM module can be built, delivering enough capacity for next-generation GPUs. At a transfer rate of up to 32Gbps (per Samsung’s official announcement), it supports ultra-high bandwidth for AI computing, real-time 3D rendering, and advanced gaming workloads.
Energy Efficiency
Samsung’s 24Gb GDDR7 adopts refined circuit design and advanced low-power signaling, providing up to 30% higher power efficiency compared to GDDR6, which helps reduce energy costs in AI data centers and lowers heat generation in high-end gaming graphics cards.
AI & Enterprise Applications
The 24Gb density enables graphics accelerators to handle large-scale AI training datasets and next-generation rendering tasks without frequent offloading to system memory. This enhances performance in both consumer (gaming) and enterprise (AI/ML, VFX rendering) markets.
Application Cases by Model
Application of 16Gb Samsung GDDR7 DRAM IC in Mid-Range Gaming Laptops
A well-known brand has launched a mid-range gaming laptop equipped with a discrete graphics card (4GB VRAM) using 16Gb Samsung GDDR7 DRAM IC. In real-world usage, when users run mainstream e-sports games such as League of Legends and CS2, the high transfer rate of the 16Gb Samsung GDDR7 DRAM IC plays a key role. Taking CS2 as an example: under 2K resolution and maximum graphics settings, the game needs to load map textures, player models, and dynamic smoke effects in real time. The 72GB/s single-chip transfer rate of the 16Gb Samsung GDDR7 DRAM IC can quickly transmit this data to the graphics card core, maintaining a stable game frame rate of over 144 FPS—meeting e-sports players’ demand for high refresh rates.
At the same time, its 1.2V low operating voltage effectively reduces graphics card power consumption. When the gaming laptop runs on battery power alone, it can maintain 2.5 hours of battery life while playing League of Legends (1080P graphics)—30 minutes longer than models with the same configuration using GDDR6 memory. Additionally, the compatibility of the 78-ball FBGA package eliminates the need for graphics card manufacturers to adjust PCB design, reducing product development costs and allowing the gaming laptop to be priced in the mid-range segment, making it a cost-effective consumer product.
Application of 24Gb Samsung GDDR7 DRAM IC in High-End Graphics Cards and AI Accelerators
A leading GPU manufacturer has introduced a new high-end graphics card equipped with 24GB VRAM using 24Gb Samsung GDDR7 DRAM IC. With a per-pin speed of up to 32Gbps and module bandwidth exceeding 1.5TB/s, this GPU can handle massive datasets for both gaming and professional workloads.
When running next-generation AAA titles such as Cyberpunk 2077 with ray tracing enabled at 4K resolution, the 24GB VRAM capacity ensures that high-resolution textures, lighting data, and AI-driven effects are cached locally, minimizing frame drops and improving average frame rates by more than 20% compared to previous-generation 16Gb-based models.
In enterprise applications, the same 24Gb GDDR7 DRAM IC is applied in AI accelerator cards for training large language models (LLMs). With higher density and improved energy efficiency (30% better than GDDR6), these accelerators can store larger training batches in memory, reducing data transfer bottlenecks. Benchmarks show that training throughput for a 70B-parameter model increases by 15% compared to accelerators using GDDR6 memory.
Moreover, its optimized signaling and low-power design reduce heat generation, allowing data centers to lower cooling costs while maintaining high-performance AI workloads. This balance of performance and efficiency positions the 24Gb Samsung GDDR7 DRAM IC as a cornerstone for both advanced gaming graphics cards and next-generation AI infrastructure.
