There's a handful of competitors vying for the top spot when it comes to smartphone chipmaking, and new data from Strategy Analytics shows Apple (NASDAQ:AAPL) made slight gains in smartphone processor revenue share last quarter. 

But while there's lots of fluctuation between the top processor competitors, Qualcomm's (NASDAQ:QCOM) revenue share stays well on top.

When the chips are down
In the second quarter of this year, Apple beat out Intel, Samsung, MediaTek, and Broadcom to take the No. 2 spot in smartphone processor revenue share.

Though Apple doesn't fabricate its own chips, or sell designs to other companies, Strategy Analytics calculated Apple's revenue numbers from market-level average selling prices and unit shipments.

Here's how Apple stacks up against some of the competition:

While Apple's percentage doesn't come close to matching Qualcomm's, it's important for investors to remember two things: First, Qualcomm's core business is in making chips; Apple's is not. Second, Apple has remained a steady competitor over the past year, while Samsung has fallen to the No. 4 spot.

A year ago, Apple had a 16% smartphone processor revenue share, so despite dropping to 15% this year, the company has remained relatively fixed.

Even given Apple's strong position, it's overshadowed by Qualcomm's obvious dominance in the space. Part of the chipmaker's status is attributed to its advancements in LTE, which have outpaced all competitors to date. But it's also the fact that Qualcomm has relationships with many original equipment manufacturers and has design wins in major flagship devices like the HTC One, Samsung Galaxy S4, and Sony Xperia Z. This has helped increase Qualcomm's smartphone revenue share from 43% in 2012 to its current 53%.

MediaTek is attempting to take on Qualcomm's position and recently said it's working on a 64-bit processor and integrated LTE system-on-a-chip technologies. Though Qualcomm's current position is still very strong, increased competition from MediaTek and others will help drive down the cost of LTE devices, and could eventually hurt Qualcomm's dominance.

The one thing for investors to remember is the mobile processor revenue space fluctuates quarter by quarter, and while most of the big players will remain in the top positions, their places may shift. So while Apple has done well against smartphone processor competitors over the past year, the most stable player is Qualcomm. Though MediaTek and others will try to take more processor revenue share from the company, investors should remember that Qualcomm's technology, relationships with OEMs, and its first-mover advantage in LTE will make the company a formidable opponent against anyone attempting to take its No. 1 spot.
