Graphics cards to get more expensive, board partners raise prices

Graphics, News | | Jan Olšan

Most hardware is getting more expensive and unfortunately graphics cards are joining the trend. According to Asian sources, major board partners are now raising GPU prices due to increasing costs of GDDR6 and GDDR7 graphics memory. In the short term, this is expected to push prices up by 15–20 %. That may not be the final outcome, however, as further increases could be driven by reduced GPU supply due to supply-and-demand dynamics.

Overclocking RX 9070 XT Memory: Samsung or Hynix — Who Wins?

Extra tests, Graphics | | Adam Vágner

Manufacturers ship RX 9070 XT cards with GDDR6 memory from either Hynix or Samsung. Clocks are the same, yet performance and thermals can differ slightly—and the same goes for overclocking. Samsung chips tend to reach higher memory clocks, which suggests better performance, but it isn’t that simple. We will compare the practical differences between both variants using the same card: Gigabyte’s Radeon RX 9070 XT Gaming OC.

Hynix vs Samsung on RX 9070 XT: in-depth GDDR6 thermal analysis

Extra tests, Graphics | | Adam Vágner

Radeon RX 9070 XT cards use GDDR6 from multiple vendors. The biggest differences between Samsung and Hynix appear in temperature and power—Samsung runs notably cooler. Earlier tests with automatic fan control confirmed this. Today I’m adding a temperature comparison at equal fan speeds and, alongside internal sensor data, surface temperatures measured on the chips. That gap is much smaller than expected. Read more “Hynix vs Samsung on RX 9070 XT: in-depth GDDR6 thermal analysis” »

Radeon RX 9070 XT: Samsung or Hynix? GDDR6 performance test

Extra tests, Graphics | | Adam Vágner

I already compared the clocks, temperatures, and power consumption of two samples of the same model, the Gigabyte AMD Radeon RX 9070 XT Gaming OC. They differed in memory—the first had Hynix GDDR6 chips and the second Samsung. However, the two tests were months apart. Now I have both units on hand, so I can test performance under identical conditions. We’ll also look at the impact of enabling the fast memory timing option.

Same Radeon RX 9070 XT, Different GDDR6: Samsung vs. Hynix

Extra tests, Graphics | | Adam Vágner

Over a few months, two nearly identical Gigabyte RX 9070 XT Gaming OC cards passed through my hands. They use GDDR6 chips from different manufacturers. The older card had Hynix; the newer uses Samsung GDDR6, known for lower power draw and temperatures. We’ll examine how this change affects performance, memory temperatures and power, GPU temperatures and clock speeds, and overall card power consumption in our tests.

Samsung will make GDDR6 50% faster than today, already sampling

Graphics, News | | Jan Olšan

Since HBM2E is no longer used in gaming GPUs due to its price, the highest performing graphic memory is now the PAM4-based GDDR6X, developed by Micron for Nvidia and reaching transfer rates of up to 21.0 GHz. However, it could now be outperformed by the classic GDDR6. Samsung has announced 20GHz and even 24GHz samples of GDDR6 (or GDDR6+?), that could bring about a 50% bandwidth increase when compared to current GDDR6.

Future of memory tech: Samsung on DDR6, GDDR7 and GDDR6+

Memory, News | | Jan Olšan

DDR5 memory modules for PCs have arrived on the market only recently so their replacement should be many years away (the span between the introduction of DDR4 and DDR5 has been more than seven years). But Samsung, as one of the main memory modules producers, has now announced more distant plans for the successors of the DDR5 memory (DDR6), but also new graphic memory, to replace GDDR6 and GDDR6X at the Tech Day 2021 conference.

Ampere GPU: new PAM4-based GDDR6X memory & more details

Graphics, News | | Jan Olšan

Next-gen Nvidia GeForce GPUs are almost here, with reveal on September 1th, but we have interesting new information on them like some specs for the RTX 3080 and RTX 3090. But more importantly, it turns out Ampere introduces a complely new memory. Micron has confirmed developping special GDDR6X chips for Nvidia that will increase clocks and bandwidth by 50% over GDDR6. So what do we know so far? Read more “Ampere GPU: new PAM4-based GDDR6X memory & more details” »
