AMD CDNA Architecture : Tech Highlights!

In addition to the gaming-centric RDNA architecture, AMD just introduced a new CDNA architecture that is optimised for compute workloads.

Here are some key tech highlights of the new AMD CDNA architecture!

 

AMD CDNA Architecture : What Is It?

Unlike the fixed-function graphics accelerators of the past, GPUs are now fully-programmable accelerators using what’s called the GPGPU (General Purpose GPU) Architecture.

GPGPU allowed the industry to leverage their tremendous processing power for machine learning and scientific computing purposes.

Instead of continuing down the GPGPU path, AMD has decided to introduce two architectures :

  • AMD RDNA : optimised for gaming to maximise frames per second
  • AMD CDNA : optimised for compute workloads to maximise FLOPS per second.

Designed to accelerate compute workloads, AMD CDNA augments scalar and vector processing with new Matrix Core Engines, and adds Infinity Fabric technology for scale-up capability.

This allows the first CDNA-based accelerator – AMD Instinct MI100 – to break the 10 TFLOPS per second (FP64) barrier.

The GPU is connected to its host processor using a PCI Express 4.0 interface, that delivers up to 32 GB/s of bandwidth in both directions.

 

AMD CDNA Architecture : Compute Units

The command processor and scheduling logic receives API-level commands and translates them into compute tasks.

These compute tasks are implemented as compute arrays and managed by the four Asynchronous Compute Engines (ACE), which maintain their independent stream of commands to the compute units.

Its 120 compute units (CUs) are derived from the earlier GCN architecture, and organised into four compute engines that execute wavefronts that contain 64 work-items.

The CUs are, however, enhanced with new Matrix Core Engines, that are optimised for matrix data processing.

Here is the block diagram of the AMD Instinct MI100 accelerator, showing how its main blocks are all tied together with the on-die Infinity Fabric.

Unlike the RDNA architecture, CDNA removes all of the fixed-function graphics hardware for tasks like rasterisation, tessellation, graphics caches, blending and even the display engine.

CDNA retains the dedicated logic for HEVC, H.264 and VP9 decoding that is sometimes used for compute workloads that operate on multimedia data.

The new Matrix Core Engines add a new family of wavefront-level instructions – the Matrix Fused Multiply-Add (MFMA). The MFMA instructions perform mixed-precision arithmetic and operates on KxN matrices using four different types of input data :

  • INT8 – 8-bit integers
  • FP16 – 16-bit half-precision
  • bf16 – 16-bit brain FP
  • FP32 – 32-bit single-precision

The new Matrix Core Engines has several advantages over the traditional vector pipelines in GCN :

  • the execution unit reduces the number of register file reads, since many input values are reused in a matrix multiplication
  • narrower datatypes create opportunity for workloads that do not require full FP32 precision, e.g. machine learning – saving energy.

 

AMD CDNA Architecture : L2 Cache + Memory

Most scientific and machine learning data sets are gigabytes or even terabytes in size. Therefore L2 cache and memory performance is critical.

In CDNA, the L2 cache is shared across the entire chip, and physically partitioned into multiple slices.

The MI100, specifically, has an 8 MB cache that is 16-way set-associative and made up of 32 slices. Each slice can sustain 128 bytes for an aggregate bandwidth of over 6 TB/s across the GPU.

The CDNA memory controller can drive 4- or 8-stacks high of HBM2 memory at 2.4 GT/s for a maximum throughput of 1.23 TB/s.

The memory contents are also protected by hardware ECC.

 

AMD CDNA Architecture : Communication + Scaling

CDNA is also designed for scaling up, using the high-speed Infinity Fabric technology to connect multiple GPUs.

AMD Infinity Fabric links are 16-bits wide, and operate at 23 GT/s, with three links in CDNA to allow for full connectivity in a quad-GPU configuration.

While the last generation Radeon Instinct MI50 GPU only uses a ring topology, the new fully-connected Infinity Fabric topology boosts performance for common communication patterns like all-reduce and scatter / gather.

Unlike PCI Express, Infinity Fabric links support coherent GPU memory, which lets multiple GPUs share an address space and tightly work on a single task.

NVIDIA TITAN V – The First Desktop Volta Graphics Card!

NVIDIA CEO Jensen Huang (recently anointed as Fortune 2017 Businessperson of the Year) made as surprise reveal at the NIPS conference – the NVIDIA TITAN V. This is the first desktop graphics card to be built on the latest NVIDIA Volta microarchitecture, and the first to use HBM2 memory.

In this article, we will share with you everything we know about the NVIDIA TITAN V, and how it compares against its TITANic predecessors. We will also share with you what we think could be a future NVIDIA TITAN Vp graphics card!

Updated @ 2017-12-10 : Added a section on gaming with the NVIDIA TITAN V [1].

Originally posted @ 2017-12-09

 

NVIDIA Volta

NVIDIA Volta isn’t exactly new. Back in GTC 2017, NVIDIA revealed NVIDIA Volta, the NVIDIA GV100 GPU and the first NVIDIA Volta-powered product – the NVIDIA Tesla V100. Jensen even highlighted the Tesla V100 in his Computex 2017 keynote, more than 6 months ago!

Yet there has been no desktop GPU built around NVIDIA Volta. NVIDIA continued to churn out new graphics cards built around the Pascal architecture – GeForce GTX 1080 Ti and GeForce GTX 1070 Ti. That changed with the NVIDIA TITAN V.

 

NVIDIA GV100

The NVIDIA GV100 is the first NVIDIA Volta-based GPU, and the largest they have ever built. Even using the latest 12 nm FFN (FinFET NVIDIA) process, it is still a massive chip at 815 mm²! Compare that to the GP100 (610 mm² @ 16 nm FinFET) and GK110 (552 mm² @ 28 nm).

That’s because the GV100 is built using a whooping 21.1 billion transistors. In addition to 5376 CUDA cores and 336 Texture Units, it boasts 672 Tensor cores and 6 MB of L2 cache. All those transistors require a whole lot more power – to the tune of 300 W.

[adrotate group=”1″]

 

The NVIDIA TITAN V

That’s V for Volta… not the Roman numeral V or V for Vendetta. Powered by the NVIDIA GV100 GPU, the TITAN V has 5120 CUDA cores, 320 Texture Units, 640 Tensor cores, and a 4.5 MB L2 cache. It is paired with 12 GB of HBM2 memory (3 x 4GB stacks) running at 850 MHz.

The blowout picture of the NVIDIA TITAN V reveals even more details :

  • It has 3 DisplayPorts and one HDMI port.
  • It has 6-pin + 8-pin PCIe power inputs.
  • It has 16 power phases, and what appears to be the Founders Edition copper heatsink and vapour chamber cooler, with a gold-coloured shroud.
  • There is no SLI connector, only what appears to be an NVLink connector.

Here are more pictures of the NVIDIA TITAN V, courtesy of NVIDIA.

 

Can You Game On The NVIDIA TITAN V? New!

Right after Jensen announced the TITAN V, the inevitable question was raised on the Internet – can it run Crysis / PUBG?

The NVIDIA TITAN V is the most powerful GPU for the desktop PC, but that does not mean you can actually use it to play games. NVIDIA notably did not mention anything about gaming, only that the TITAN V is “ideal for developers who want to use their PCs to do work in AI, deep learning and high performance computing.

[adrotate group=”2″]

In fact, the TITAN V is not listed in their GeForce Gaming section. The most powerful graphics card in the GeForce Gaming section remains the TITAN Xp.

Then again, the TITAN V uses the same NVIDIA Game Ready Driver as GeForce gaming cards, starting with version 388.59. Even so, it is possible that some or many games may not run well or properly on the TITAN V.

Of course, all this is speculative in nature. All that remains to crack this mystery is for someone to buy the TITAN V and use it to play some games!

The NVIDIA TITAN Vp?

In case you are wondering, the TITAN Vp does not exist. It is merely a hypothetical future model that we think NVIDIA may introduce mid-cycle, like the NVIDIA TITAN Xp.

Our TITAN Vp is based on the full capabilities of the NVIDIA GV100 GPU. That means it will have 5376 CUDA cores with 336 Texture Units, 672 Tensor cores and 6 MB of L2 cache. It will also have a higher TDP of 300 watts.

NVIDIA Tesla P100 For PCIe-Based Servers Overview

On June 20, 2016, NVIDIA officially unveiled their Tesla P100 accelerator for PCIe-based servers. This is a long-expected PCI Express variant of the Tesla P100 accelerator that was launched in April using the NVIDIA NVLink interconnect. Let’s check out what’s new!

 

NVIDIA Tesla P100

The NVIDIA Tesla P100 was originally unveiled at the GPU Technology Conference on April 5, 2016. Touted as the world’s most advanced hyperscale data center accelerator, it was built around the new NVIDIA Pascal architecture and the proprietary NVIDIA NVLink high-speed GPU interconnect.

Like all other Pascal-based GPUs, the NVIDIA Tesla P100 is fabricated on the 16 nm FinFET process technology. Even with the much smaller process technology, the Tesla P100 is the largest FinFET chip ever built.

Unlike the Pascal-based GeForce GTX 1080 and GTX 1070 GPUs designed for desktop gaming though, the Tesla P100 uses HBM2 memory. In fact, the P100  is actually built on top of the HBM2 memory chips in a single package. This new package technology, Chip on Wafer on Substrate (CoWoS), allows for a 3X boost in memory bandwidth to 720 GB/s.

The NVIDIA NVLink interconnect allows up to eight Tesla P100 accelerators to be linked in a single node. This allows a single Tesla P100-based server node to outperform 48 dual-socket CPU server nodes.

 

Now Available With PCIe Interface

To make Tesla P100 available for HPC (High Performance Computing) applications, NVIDIA has just introduced the Tesla P100 with a PCI Express interface. This is basically the PCI Express version of the original Tesla P100.

 

Massive Leap In Performance

Such High Performance Computing servers can already make use of the NVIDIA Tesla K80 accelerators, that are based on the previous-generation NVIDIA Maxwell architecture. The new NVIDIA Pascal architecture, coupled with much faster HBM2 memory, allow for a massive leap in performance. Check out these results that NVIDIA provided :

Ultimately, the NVIDIA Tesla P100 for PCIe-based servers promises to deliver “dramatically more” performance for your money. As a bonus, the energy cost of running Tesla P100-based servers is much lower than CPU-based servers, and those savings accrue over time.

[adrotate banner=”5″]

 

Two Configurations

The NVIDIA Tesla P100 for PCIe-based servers will be slightly (~11-12%) slower than the NVLink version, turning out up to 4.7 teraflops of double-precision performance, 9.3 teraflops of single-precision performance, and 18.7 teraflops of half-precision performance.

The Tesla P100 will be offered in two configurations. The high-end configuration will have 16 GB of HBM2 memory with a maximum memory bandwidth of 720 GB/s. The lower-end configuration will have 12 GB of HBM2 memory with a maximum memory bandwidth of 540 GB/s.
