Review: AMD FirePro W4300 graphics card

AMD FirePro W4300 – AMD has managed to pack a powerful mid-range GPU into a low profile graphics card. CAD users no longer have to compromise on 3D performance to get the space saving benefits of a Small Form Factor (SFF) workstation, writes Greg Corke

They say the best things come in small packages, but with workstations, the diminutive desktop has always come with performance trade-offs.

Could we see the AMD FirePro W4300 in the HP Z240 SFF?

Small Form Factor (SFF) workstations are around 60-70% smaller than a standard mini tower. But the slimline chassis demands a special low profile graphics card with a significantly smaller footprint. With less silicon on board, these custom GPUs have historically been limited in terms of performance.

Entry-level graphics is perfectly fine if you only work with small CAD assemblies but with larger models or with realistic viewport shading and lighting, frame rates can drop considerably making models jump about on screen.

Despite the limitations the SFF workstation continues to grow in popularity and graphics card manufacturers have sensed an opportunity. Rather than limit sales to entry-level designers, engineers and architects they are now developing low profile GPUs for more demanding 3D CAD users.


Nvidia kicked things off earlier this year with the launch of the low profile Quadro K1200 (4GB). It was a big step up from the entry-level Quadro K620, as we noted in our review of the Lenovo ThinkStation P300 SFF workstation earlier this year.

However, there still remained a sizeable performance gap between it and mid-range Quadro K2200 (4GB), a popular choice for mainstream 3D CAD tower workstations.

AMD has now upped the ante with the launch of the AMD FirePro W4300, a 4GB low profile GPU that delivers virtually the same graphics horsepower as AMD’s mid-range offering, the FirePro W5100.

AMD FirePro W4300 – Mid-range, small package

On paper the AMD FirePro W4300 and AMD FirePro W5100 appear very alike.

Both feature 4GB GDDR5 memory with 96GB/sec memory bandwidth, 1.43 GFLOPS of single precision floating point performance and four DisplayPort outputs (the FirePro W4300 has mini DisplayPort). And, as our tests confirm, performance is also remarkably similar. Not surprisingly, this is reflected in the price.

With an MSRP of $379 the AMD FirePro W4300 costs just $20 less than the AMD FirePro W5100.

The AMD FirePro W4300 supports up to four DisplayPort displays natively and up to six daisy-chained with DisplayPort multi-stream transport (MST). HDMi, DVI, even VGA displays can also be used with appropriate adapters.

With AMD Eyefinity, the card has the ability to span a CAD model across multiple tiled displays. Doing so with 4K and 5K displays though would likely put a significant strain on the GPU, perhaps best left to higher end cards.

We tested the AMD FirePro W4300 running our standard SolidWorks 2015 and PTC Creo 3.0 SPECapc benchmarks on a single 1,920 x 1,080 display.

Our test workstation, an HP Z240 Mini Tower, was chosen so we could compare performance with the full height FirePro W5100 and Nvidia Quadro K2200 GPUs.

The SolidWorks 2015 SPECapc benchmark captures a broad range of display states from shaded and edges and shadows to Realview and Ambient Occlusion.

The test can be run with Full Scene Anti Aliasing (FSAA) (a rendering mode that smoothes jagged edges) enabled and disabled.

The PTC Creo 3.0 SPECapc benchmark runs in shaded and edges, reflections and wireframe modes. The results were quite astounding.

Under SolidWorks with FSAA disabled the FirePro W4300 was 10% faster on average than the Nvidia Quadro K2200. But with FSAA enabled it was more than twice as fast (we imagine this is the same Quadro K2200 performance issue we first wrote about in August.

The FirePro W4300 features four mini DisplayPort outputs

Under PTC Creo, however, the Nvidia Quadro K2200 had the lead, clocking in around 20% faster.

As mentioned earlier, the AMD FirePro W4300 was only a fraction behind the AMD FirePro W5100 in both SolidWorks and Creo (between 2% and 5%).


The AMD FirePro W4300 is a hugely impressive graphics card that delivers true mid-range performance in a low profile form factor.

As the card is so new, the major workstation OEMs have yet to announce whether or not they will be supporting it.

We certainly hope they do, as it should bring an exciting new edge to SFF workstations, making them capable of satisfying the 3D requirements of the most demanding Inventor, PTC Creo and SolidWorks users.

Considering new generation ‘Skylake’ SFF workstations like the HP Z240 SFF and Dell Precision 3420, can also host up to 64GB memory, fast M.2 PCIe NVMe Solid State Drives (SSDs) together with high capacity SATA hard disk drives (HDDs) suddenly the entry-level SFF workstation doesn’t look that entry-level anymore.
