So how does this all translate into real world performance? While both cards feature 480 stream processors, the FirePro V4900 runs its cores approx 20% faster in terms of GHz. There’s also a performance difference in terms of the Graphics Processing Unit (GPU). The FirePro V3900 only features DDR3, which delivers a bandwidth of 29GB/sec, while the FirePro V4900 sports GDDR5 memory, the same type used in AMD’s higher end cards, to boost memory bandwidth to 64GB/sec. While the memory capacity is the same for both cards, there’s a significant difference in memory performance. It’s safe to say that, for mainstream CAD, AMD’s new cards won’t have the limitations of legacy cards, which may have struggled with 128MB or 256MB. To put this in context it’s important to understand that graphics memory has become more significant for CAD/CAM applications, particularly with technologies such as Vertex Buffer Object (VBO), a feature of OpenGL that loads geometry onto the card to boost performance.Įven with these increased demands, the 1GB threshold is unlikely to be breached until you get into the realms of automotive or aerospace sized assemblies. Both cards are based on AMD’s latest generation ‘Turks’ architecture and boast 1GB of frame buffer memory, a considerable amount for an entry-level CAD card. When it comes to mainstream CAD, ‘underspecified’ is a criticism that can’t be levied at AMD’s new entry-level cards, the FirePro V3900 and V4900. Entry-level cards were cheap (sub £100) but sometimes a little underspecified or lacking in the latest features. In the past this balance wasn’t always found. The challenge is to keep prices low, while still offering cards capable of handling CAD assemblies that are not insignificant in size. AMD and Nvidia not only compete with each other, but with their own consumer brands, Radeon and GeForce.
