Why the RTX 4080 12GB feels a lot like a rebranded RTX 4070

Nvidia announced two versions of its RTX 4080 at its GTC keynote — a 12GB model and a 16GB model. On the surface, this seems simple. Two configurations of the same graphics cards, except with different amount of memory.

This is, after all, what Nvidia did with its RTX 3080 last year. There was the original 8GB RTX 3080, and the 12GB RTX 3080 that got released earlier this year.

But the situation with the two “versions” of the RTX 4080 couldn’t be more different. Not only is there a $300 gulf in price between these two products, but Nvidia confirmed to the media today that they do, in fact, use two different GPUs. The RTX 4080 16GB uses AD104, and the RTX 4080 12GB uses AD103. To call these two products different “versions” of the same graphics card is a pretty serious misnomer.

Nvidia GeForce RTX 4080 16GB Nvidia GeForce RTX 4080 12GB
GPU AD104 AD103
CUDA cores 9,728 7,680
Shader / RT cores 49 / 113 40 / 82
Tensor TFLOPS 780 641
Base clock 2,210MHz 2,310MHz
Maximum clock 2,510MHz 2,610MHz
Memory size 16GB GDDR6X 12GB GDDR6X
Memory bus 256-bit 192-bit
TDP 320 watts 285 watts
Price $1,199 $899

Looking at the other specs we now have, you can see how that plays out. The RTX 4080 16GB has 21% more CUDA cores, 27% more RT cores, and is capable of 18% more Tensor TFLOPS (trillion floating-point operations per second) than the 12GB model. Of course, it also has a wider memory bus and consumes more power too. All in all, the 16GB model is a much more powerful graphics card.

So, what then is going on with the naming of this 12GB RTX 4080? Well, just look at what Nvidia did with its initial launch of the first RTX 30-series cards. At launch, the company announced the RTX 3090, 3080, and 3070. Three GPUs down the line. What it’s doing with the RTX 40-series line is nearly identical, meaning the 12GB 4080, which retails for $899, feels a lot more like a proper RTX 4070 than anything else. That’s a problem, considering the RTX 3070 retailed for just $499.

When asked, of course, Nvidia sees the 16GB model as an “enhanced” RTX 4080, not the other way around. And maybe the company has a point, at least with how these cards are priced. The 16GB model is certainly priced as if it were an RTX 4080 Ti — or something along those lines. Nvidia has also confirmed that there will be no first-party Founders Edition of the 12GB RTX 4080.

Still, the whole thing has left a sour taste in the mouths of PC enthusiasts, who are looking at this 12GB RTX 4080 as a repackaged 4070 as a way to secretly raise prices. Nvidia hasn’t been shy about commenting on the rising cost of GPUs in the future, confirming that falling prices are a thing of the past.

We’ll have to wait and see what Nvidia eventually does with the rest of the lineup to get the full picture, but at the very least, it’s obvious that GPU pricing is continuing to rise, even if some of the costs are buried in the specs.

Qualcomm’s Snapdragon 7c feels like a fit for Acer’s Chromebook Spin 5

If Qualcomm’s Snapdragon platforms have struggled in PCs, could they succeed within Chromebooks? That’s the question Acer’s new Chromebook Spin 5 asks, and the answer certainly feels like a “yes.”

To date, Qualcomm has emphasized the performance of its Snapdragon 8cx and the related Snapdragon 8cx Gen 2 5G platform, both chips that have tried to take on Intel’s Core i5 in the Windows PC space. When Qualcomm debuted the even slower Snapdragon 8c and 7c last December on a Windows PC, it was a head-scratcher: If the 8cx couldn’t compete, what was the justification for a slower, cheaper chip?

Now we know: Chromebooks.

Acer’s Chromebook Spin 513 (CP513-1H / CP513-1HL) and the related Chromebook Enterprise Spin 513 are designed around the Snapdragon 7c. Snapdragon’s traditional strengths are at play here: The chip allows the Spin 513 to get up to 14 hours of battery life, depending on workloads and the backlighting level. Optional 4G LTE is enabled by the 7c platform, too. The Spin 513 also weighs about 2.64 pounds—light weight is typically another characteristic of the Snapdragon platform.

The Spin 513 includes a 13.3-inch IPS 1080p display, which as a 360-degree convertible can pivot backward into tablet mode. Because it’s a modern Chromebook, the Spin 513 runs Android apps. Inside is up to 8GB of LPDDR4X SDRAM, up to 128GB of storage, and 802.11ac Wi-Fi and Bluetooth 5.0. Externally, there’s a pair of USB-C ports that support USB 3.2 Gen 2 as well as external displays, plus a USB 3.2 port (with external charging).

Qualcomm claimed previously that the Snapdragon 7c chip will offer up to 20 percent better performance over the Snapdragon 850, the chip which powered tablets like the Samsung Galaxy Book 2. Qualcomm paired the octa-core Kryo 468 with the Adreno 618 GPU and the Snapdragon X15 LTE modem.

Looking back at reviews like the Samsung Galaxy Book S, we can see that the Snapdragon’s generally slow performance, on top of its inability to run 64-bit Windows apps, hurt its ability to compete with a Core chip. With Chromebooks, these issues go away.

We can’t say for certain what the Snapdragon 7c’s performance will be, but we can say that the first Chromebook with the Snapdragon 7c inside will certainly perform as well as the legacy ARM chips that have populated Chromebooks in the past, including older Nvidia Tegra chips, older MediaTek components, and the like. With a lack of CPU-intensive apps to take advantage of the platform—save for a few Android games—light weight, long battery life and all-day connectivity in a Chromebook would seem to be equal to, or more desirable than, cramming in an older Intel Celeron.
