Review video cards AMD Radeon R9 Fury X: A New Hope

Introduction

In view of the current situation on the market of graphics accelerators, AMD had no choice but to gather strength and to develop on the familiar 28-nm process technology the new GPU – Fiji . In truth, it is only partly new. But all the same time gradually passed, and wait longer was impossible.

On the other hand, Nvidia engineers for the period immediately fired three quick graphics card – GeForce GTX 980, GTX 980 Ti and GTX Titan X. To fight the first cast new revision of Hawaii with their frequencies, and with the support of 8 GB of memory. And the latest model plays in a different league. Of all the trio needed only contender for the GTX 980 Ti, has a good performance and a decent price. That is why most of the effort was spent on the development of Radeon R9 Fury X .

In addition to creating a new model is positioned as a leader, AMD has worked in parallel with the manufacturer of the memory, in order to ensure its new product maximum innovation. On the type of memory HBM (High Bandwidth Memory) we have рассказывали before . It is time to show how it is combined with the graphics core.

 Radeon R9 Fury X: HBM + GPU

This type of memory is carried away from the GPU, met him only in the laboratory. The process of reunification is not simple and requires more attention. The fact that the connection crystal is very fragile. Hence the warning engineers AMD – in any case do not remove the cooling system with a Radeon R9 Fury X. But we have experienced people and we know how to handle fragile things.

But back to the topic. Connecting the crystals are grown at a factory partners AMD, and each contains a layer 22!

The initial stage of production of the connecting plate It begins with a “waffle.” According to some physical characteristics it is very similar to the birth of GPU or CPU, only slightly thinner.

The slide AMD several mistaken, and “mm” should be read as a micrometer. Take the 750 m and plate it to a depth of 100 m makes a hole for the first layer connections.

Next, a layer of silicon dioxide.

And then formed a base layer of metal compounds (copper). Then the grown through careful polished and preparing to move to the second stage of the assembly.

In physical terms: the hole with ready-copper compounds have a diameter of 10-11 mm, the distance between the centers – 45 microns.

Under the microscope, they look like neatly drilled holes with a small bevel top.

further strengthen FS RDL. Translated into Russian – a special layer for routing the connecting channels in the JEDEC-compatible format.

Simply put, the adapter layer that combines I / O memory to the JEDEC standard. It consists of a combination of chemicals, such as copper, dielectrics and other.

On top of a layer that protects the newly formed substrate damage and direct contact with the adhesive, which in future will be in contact through the holes in this layer.

Sami hole beads solder paste is made later, and they are upside down and bottom. For now it’s just a piece of crystal with thousands of trunks.

Next, the substrate is inverted. Her ex-connect with the top layer, and the type of memory supports HBM, and the graphics processor.

Further assembly process is carried out at another plant where the insert is cleaned by connecting the transport glue on it rolled balls of solder paste, it is attached to the PCB. And that’s when the memory test is done in conjunction with the GPU.

Layer connections in practice is very fragile. Imagine a sandwich of layers 22, where at least half of – the glass, and between them is located a foil. It is necessary to push harder, and it bursts. Because of this fear and took representatives of AMD, that journalists will bring GPU damaged when dismantling inaccurate cooling system. However, to her I will come back, because there are some nuances that are worth to know.

 

 Radeon R9 Fury X: GPU Fiji

At a press conference about the device and specific changes within the video core engineers rarely share details. All that we know – is that the graphics processor is built on the architecture of Fiji GCN 1.2.

It also produced a video card R9 285, respectively, and R9 380. As you know, former classmates as Tahiti Tonga we will not see.

Functional diagram as the Fiji two drops of water similar in structure to Tonga. From it we have a chart.

In Fiji the same 4 shader engine, but not everyone comes to 7, and 16 execution units. Cache memory is increased to 2 Mbytes. Changed memory controllers to support HBM.

On the question of whether the Fiji type of memory HBM2, we subtly hinted that anything is possible. Thus, we can assume that after HBM2 fast enough, AMD will release an updated version.

Accordingly, other changes were told very little. Even the question of support for HDMI 2.0 was stingy response that it does not exist, and it is likely to appear only after the market will be quite compatible devices. And for the most impatient offers active DisplayPort adapter for HDMI 2.0
