The WS AR-X6700 makes good use of its £4,500 budget, with a solid balance of components. Workstation Specialists has chosen the AMD Ryzen 9 7950X, which offers 16 cores and 32 threads, with a base 4.5GHz clock and boost up to 5.7GHz. This is backed by 64GB of RAM, provided as two DIMMs, so there’s room to upgrade. It’s 5,200MHz DDR5, which the Ryzen 7000 series now supports.
Graphics acceleration comes from the Nvidia RTX A5000. With a hefty 8,192 CUDA cores and 24GB of GDDR6 frame buffer on a 384-bit bus offering 768GB/sec of bandwidth, it’s a potent workstation accelerator. Its quartet of DisplayPort 1.4a connections support up to four 4K screens at 120Hz, or two 8K screens at 60Hz.
Apart from the decidedly skinny Lenovo chassis, the Fractal Design Define C Tempered Glass case here is the most compact this month. There’s still room for a couple of 3.5in or 2.5in drives, plus up to three 2.5in units. The only storage supplied, however, is a 2TB Samsung 990 Pro NVMe SSD, which when tested with CrystalDiskMark 8.0.4 delivered competent 7,457MB/sec sustained reading and 6,915MB/sec writing.
The overall result in the PC Pro benchmarks of 731 is superb compared to systems from any previous year, but in this month’s company it’s joint second slowest. For everyday tasks, Intel’s Core i9-13900K has the lead. The multicore rendering result in Maxon Cinebench R23 of 36,030 is similarly both excellent while still being third slowest this month. The Blender Gooseberry render took 282 seconds with the CPU, however, which is more competitive.
Sadly, with so many powerful systems in this test, the Nvidia RTX 5000 manages performance only in the middle of the pack. Looking at the SPECviewperf 2020 v3.1 results, the score of 178 in 3dsmax-07 is the third slowest, although 535 in maya-06 is a bit higher up the rankings. Only Lenovo’s P620, with its RTX A4000, consistently falls behind. The OpenCL rendering result in LuxMark 3.1 of 15,489 is in line with our expectations for an RTX A5000, while GPU rendering with Blender took 148 seconds, which is also mid-range.
Overall, while the Workstation Specialists WS AR-X6700 is well put together and specified, it doesn’t have the leading performance of this month’s Labs Winner.
