DDR5 RAM vs CFexpress Card
Memory Speed
The Lexar Thor Z RGB DDR5 RAM operates at 6000 MHz, delivering high-frequency bandwidth for your desktop system. This speed helps your CPU access data quickly, which is vital for gaming and heavy multitasking. In contrast, the Lexar Gold Series Professional CFexpress card offers read speeds up to 1800 MB/s and write speeds up to 1650 MB/s. While the RAM speed is measured in MHz for system responsiveness, the card speed is measured in MB/s for file transfer rates. Both figures represent top-tier performance within their respective categories, ensuring fast data movement for their specific hardware roles.
Compatible Device
You must match the product to your hardware. The Lexar Thor Z RGB DDR5 RAM is explicitly designed for desktop PCs. It uses a 288-Pin UDIMM form factor, meaning it slots directly into your motherboard to become part of your system's active memory. The Lexar Gold Series Professional CFexpress card is designed for professional cameras and devices that accept CFexpress 4.0 Type A cards. It is not a system memory component but an external storage medium for capturing and storing media files. You cannot swap these items between a computer and a camera.
Form Factor
Physical compatibility is strict for both items. The Lexar Thor Z RGB DDR5 RAM uses a standard 288-Pin UDIMM form factor, which is the standard shape for desktop memory modules. It has a height of 0.3 inches and includes a solid aluminum heatsink for cooling. The Lexar Gold Series Professional CFexpress card follows the CFexpress 4.0 Type A standard. Its physical dimensions are 3.91 inches in length, 2.15 inches in width, and 0.51 inches in height. These distinct physical shapes ensure they fit only their intended slots, preventing any physical installation errors.
Capacity
The Lexar Thor Z RGB DDR5 RAM comes in a 32GB kit configuration, consisting of two 16GB modules. This 32GB total provides ample space for modern operating systems and applications to run smoothly without swapping data to slower storage. The Lexar Gold Series Professional CFexpress card offers a massive 2TB of storage capacity. This large volume is ideal for storing extensive high-resolution video projects and large photo libraries. While the RAM capacity affects system multitasking, the card capacity affects how much media you can capture before offloading files, making both substantial in their own contexts.
Overclocking Profile
The Lexar Thor Z RGB DDR5 RAM supports Intel XMP 3.0 and AMD EXPO overclocking profiles. These profiles allow you to easily configure your motherboard to run the memory at its rated 6000 MHz speed, ensuring stability and performance without manual tweaking. The Lexar Gold Series Professional CFexpress card does not list any overclocking profiles. Its performance is fixed by its internal controller and PCIe 4.0 interface, delivering consistent speeds up to 1800 MB/s read. Since the card is a passive storage device, you cannot adjust its speed settings, whereas the RAM offers flexibility for system tuning.
