CRN rounds up five cool AI and high-performance computing servers from Dell Technologies, Lenovo, Supermicro and Gigabyte that use AMD’s Instinct MI300 chips, which launched a few months ago to challenge Nvidia’s dominance in the AI computing space.

AMD is making its biggest challenge yet to Nvidia’s dominance in the AI computing space with its Instinct MI300 accelerator chips. A few months after launch, multiple MI300 servers are now available or set to release soon as alternatives to systems with Nvidia’s popular chips.

During the chip designer’s first-quarter earnings call Tuesday, AMD Chair and CEO Lisa Su said the MI300 has become the “fastest-ramping product” in its history after generating more than $1 billion in “total sales in less than two quarters.”

As a result, AMD now expects the MI300 to generate $4 billion in revenue this year, $500 million higher than a forecast the company gave in January.

“What we see now is just greater visibility to both current customers as well as new customers committing to MI300,” Su said.

The MI300 series currently consists of two products: the MI300X GPU, which comes with 192 GB of HBM3 high-bandwidth memory, and the MI300A APU, which combines Zen 4 CPU cores and CDNA 3 GPU cores with 128 GB of HBM3 memory on the same die.

The chips are in systems available now or coming soon from major OEMs, including Dell Technologies, Lenovo and Supermicro and Gigabyte.

The Santa Clara, Calif.-based company has pitched the MI300X as a strong competitor to Nvidia’s popular and powerful H100 data center GPU for AI training and inference. For instance, the company said its MI300X platform, which combines eight MI300X GPUs, offers 60 percent higher inference throughput for the 176-billion-parameter Bloom model and 40 percent lower chat latency for the 70B Llama 2 model compared with Nvidia’s eight-GPU H100 GHX platform.

The MI300A, on the other hand, is more aimed at the convergence of high-performance computing and AI workloads. For 64-bit floating bit calculations, AMD said the MI300A is 80 percent faster than the H100. Compared with Nvidia’s GH200 Grace Hopper Superchip, which combines its Grace GPU with an H200 GPU, the MI300A offers two times greater HPC performance, according to AMD.

For all the advantages AMD is finding with the MI300 chips, the company has to contend with the fact that Nvidia is operating on an accelerated chip road map and plans to release successors to the H100, H200 and GH200 processors later this year.

In the recent earnings call, Su said AMD’s strategy is not about one product but a “multiyear, multigenerational road map” and teased that it will share details in the “coming months” about new accelerator chips arriving “later this year into 2025.”

“We’re very confident in our ability to continue to be very competitive. Frankly, I think we’re going to get more competitive,” she said.

What follows are five cool AI and HPC servers from Dell, Lenovo, Supermicro and Gigabyte that use either AMD’s Instinct MI300X GPUs or its Instinct MI300A APUs.

With availability expected this summer, the PowerEdge XE9680’s host processors are two 4th Generation Intel Xeon Scalable CPUs, each of which provides up to 56 cores.

The server supports up to eight 2.5-inch NVMe/SAS/SATA SSD drives for a total of 122.88 TB and up to 16 E3.S NVMe direct drives for a total of 122.88 TB.

The PowerEdge XE9680 comes with the Dell OpenManage systems management software portfolio as well as security features like silicon-based root of trust.

Lenovo ThinkSystem SR685a V3

Lenovo’s recently unveiled ThinkSystem SR685a V3 is an air-cooled 8U server that is designed to tackle the most demanding AI workloads such as large language models.

Available now, the server connects eight AMD Instinct MI300X GPUs using the AMD Infinity Fabric, which gives it 1.5 TB of HBM3 high-bandwidth memory capacity and up to 1 TBps of peak aggregate I/O bandwidth. It also supports up to 3 TB of DDR5 memory across 24 DIMM slots and comes with up to 10 PCIe Gen 5 slots for attaching expansion cards.
