1 Big Reason AMD Is a Better Buy Than NVIDIA

Advanced Micro Devices (NASDAQ: AMD) and NVIDIA (NASDAQ: NVDA) have witnessed wildly different fortunes on the stock market this year. There was a time when both stocks were flying high thanks to the cryptocurrency-driven boom. But after that bubble burst last year, AMD has emerged as the stronger performer while NVIDIA has failed to recover.

It won't be surprising to see AMD stock sustain its terrific momentum and outperform NVIDIA, as the former enjoys one big advantage over its archrival.

Graphics cards are proving to be NVIDIA's Achilles' heel

NVIDIA dominates the discrete graphics processing unit (GPU) market with a share of more than 81%, leaving the rest for AMD. In fact, NVIDIA increased its GPU market share by nearly 15 percentage points last year.

But shrinking graphics card sales meant that the higher market share didn't do much for NVIDIA's financial growth. The company's fiscal first-quarter 2020 revenue fell close to 31% year over year as sales in the gaming segment were down nearly 39%. Gaming is NVIDIA's bread and butter, accounting for 47% of total revenue.

Meanwhile, NVIDIA's revenue from the "OEM and other" segment, which includes sales of GPUs for cryptocurrency mining, plunged nearly 75% annually to $99 million in the first quarter. As graphics card demand fell off a cliff after the cryptocurrency mining wave died down, the likes of NVIDIA and AMD were left with excessive channel inventory that led to lower GPU pricing.

Given NVIDIA's reliance on GPUs for the majority of its revenue, it is still reeling under the impact of an oversupplied graphics card market. AMD, however, has been able to make up for the graphics card weakness thanks to its CPU (central processing unit) business.

AMD's CPU gains have been a tailwind

Slowly but surely, AMD has been eating into CPU behemoth Intel's market share. AMD reportedly held 17% of the PC CPU market at the end of the first quarter, according to Mercury Research, up from 12% in the prior-year period. Intel holds the remaining share.

AMD's market share jump isn't surprising, as its CPUs have been selling much faster than Intel's. Looking ahead, AMD can further dent Intel's position thanks to the refreshed lineup of Ryzen chips that will hit the market next month.

AMD claims that its new Ryzen chips will deliver substantially better performance than their Intel counterparts at a much lower price. That's because the new Ryzen chips are based on a 7-nanometer manufacturing process, while Intel has now pushed back the release of its competing 10 nm CPUs to 2021.

As a result, AMD has now taken a manufacturing lead over Intel in desktop CPUs for the first time in 50 years, setting the stage for more market share gains that should enable it to stage a quick turnaround.

How CPU growth is helping AMD trump NVIDIA

AMD's revenue fell 23% year over year in the first quarter as weak demand for graphics cards knocked the wind out of its sales. This was a steep drop, but it was lower than the pace at which NVIDIA's revenue dropped last quarter.

What's more, AMD's outlook for the current quarter is for revenue to decline 13% year over year at the midpoint of its guidance range. On the other hand, NVIDIA expects its revenue to decline 19% yin the current quarter, clearly indicating that AMD is recovering faster.

Moreover, AMD reaffirmed its full-year guidance on the latest earnings conference call. The company is still expecting "high single-digit percentage revenue growth," while NVIDIA didn't reaffirm its guidance when it released its latest results.

More importantly, AMD is still a small player in CPUs and this means that AMD has a lot of room to grow its revenue on the back of more market share gains.

NVIDIA, on the other hand, is lacking on this front. It primarily deals in GPUs, and that market hasn't been in great shape. In the end, betting on AMD instead of NVIDIA makes more sense, as AMD can fall back on a secondary stream of revenue if the GPU market doesn't recover.
