Mid-Tier Snapdragon Will get Cortex-A720 Therapy

Qualcomm this morning is taking the wraps off of a brand new smartphone SoC for the mid-range market, the Snapdragon 7s Gen 3. The second of Qualcomm’s down-market ‘S’ tier Snapdragon 7 components, the 7s sequence is functionally the entry-level tier for the Snapdragon 7 household – and actually, most Qualcomm-powered handsets in North America.

With three tiers of Snapdragon 7 chips, the 7s can simply be misplaced within the noise that comes with extra highly effective chips. However the newest iteration of the 7s is a little more fascinating than regular, as moderately than reusing an present die, Qualcomm has seemingly minted an entire new die for this half. Consequently, the corporate has upgraded the 7s household to make use of Arm’s present Armv9 CPU cores, whereas utilizing bits and items of Qualcomm’s newest IPs elsewhere.

Formally, the Snapdragon 7s is classed as a 1+3+4 design – which means there’s 1 prime core, 3 efficiency cores, and 4 effectivity cores. On this case, Qualcomm is utilizing the identical structure for each the prime and effectivity cores, Arm’s current-generation Cortex-A720 design. The prime core will get to turbo as excessive as 2.5GHz, whereas the remaining A720 cores will turbo as excessive as 2.4GHz.

These are joined by the 4 effectivity cores, which, as is custom, are based mostly upon Arm’s present A5xx cores, on this case, A520. These can enhance as excessive as 1.8GHz.

In comparison with the outgoing Snapdragon 7s Gen 2, the change in Arm cores represents a reasonably important improve, changing an A78/A55 setup with the aforementioned A720/A520 setup. Notably, clockspeeds are fairly just like the earlier era half, so a lot of the unconstrained efficiency uplift on this era is being pushed by enhancements in IPC, although the sooner prime core ought to supply a bit extra kick for single-threaded workloads.

All advised, touting a 20% enchancment in CPU efficiency over the 7s Gen 2, although that declare doesn’t make clear whether or not it’s single or multi-threaded efficiency (or a combination of each).

In the meantime, graphics are pushed by certainly one of Qualcomm’s Adreno GPUs. As is normally the case, the corporate is just not providing any important particulars on the particular GPU configuration getting used – and even what era it’s. A high-level take a look at the specs doesn’t reveal any main options that weren’t current in different Snapdragon 7 components. And Qualcomm isn’t bringing high-end options like ray tracing right down to such a modest half. That mentioned, I’ve beforehand heard by the tea leaves that this can be a next-generation (Adreno 800 sequence) design; although if that’s the case, Qualcomm is definitely not making an attempt to deliver consideration to it.

Curiously, nonetheless, the video decode block on the SoC appears moderately dated. Regardless of this being a brand new die, Qualcomm has opted to not embody AV1 decoding – or, a minimum of, opted to not allow it – so H.265 and VP9 are essentially the most superior codecs supported.

In comparison with CPU efficiency good points, Qualcomm’s anticipated GPU efficiency good points are extra important. The corporate is claiming that the7s Gem 3 will ship a 40% enchancment in GPU efficiency over the 7s Gen 2.

Lastly, the Hexagon NPU block on the SoC incorporates a few of Qualcomm’s newest IP, as the corporate continues their centered AI push throughout all of their chip segments. Notably, the model of the NPU used right here will get INT4 assist for low precision shopper inference, which is new to the Snapdragon 7s household. As with Qualcomm’s different Gen 3 SoCs, the massive drive right here is for native (on-device) LLM execution.

Close to efficiency, Qualcomm says that clients ought to anticipate to see a 30% enchancment in AI efficiency relative to the 7s Gen 2.

Feeding all of those blocks is a 32-bit reminiscence controller. Apparently, Qualcomm has opted to assist older LPDDR4X even with this newer chip, so the utmost reminiscence bandwidth depends upon the reminiscence sort used. For LPDDR4X-4266 that will likely be 17GB/sec, and for LPDDR5-6400 that will likely be 25.6GB/sec. In each instances, that is similar to the bandwidth out there for the 7s Gen 2.

Rounding out the package deal, the 7s Gen 3 does incorporate some newer/extra highly effective digital camera {hardware} as properly. We’re nonetheless taking a look at a trio of 12-bit Spectra ISPs, however the most decision in zero shutter lag and burst modes has been bumped as much as 64MPix. Video recording capabilities are in any other case similar on paper, because the 7s Gen 2 already supported 4K HDR seize.

In the meantime on the wi-fi communication aspect of issues, the 7s Gen 3 packs certainly one of Qualcomm’s built-in Snapdragon 5G modems. As with its predecessor, the 7s Gen 3 helps each Sub-6 and mmWave bands, with a most (theoretical) throughput of two.9Gbps.

Eagle-eyed chip watchers will observe, nonetheless, that Qualcomm is casting off any sort of model data as of this half. So whereas the 7s Gen 2 used a Snapdragon X62 modem, the 7s Gen 3’s modem has no such designation – it’s merely an built-in Snapdragon modem. In accordance with the corporate, this variation has been made to “simplify total branding and to be per different IP blocks within the chipset.”

Equally, the Wi-Fi/Bluetooth block has misplaced its model quantity; it’s now merely a FastConnect block. With reference to options and specs, this seems to be the identical Wi-Fi 6E block that we’ve seen in half a dozen different Snapdragon SoCs, providing 2 spatial streams at channel widths as much as 160MHz. It’s price noting, nonetheless, that since this can be a newer SoC it’s licensed for Bluetooth 5.4 assist, versus the 5.2/5.3 certification different Snapdragon 7 chips have carried.

Lastly, the Snapdragon 7s Gen 3 itself is being constructed on TSMC’s N4P course of, the identical course of we’ve seen the final a number of Qualcomm SoCs use. And with this, Qualcomm has now absolutely migrated all the Snapdragon 8 and Snapdragon 7 traces off of Samsung’s 4nm course of nodes; all of their up to date chips at the moment are constructed at TSMC. And like comparable transitions prior to now, this shift in course of nodes is coming with a lift to energy effectivity. Whereas it’s not the only trigger, total Qualcomm is touting a 12% enchancment in energy financial savings.

Wrapping issues up, Qualcomm’s launch buyer for the Snapdragon 7s Gen 3 will likely be Xiaomi, who would be the first to launch a brand new cellphone with the chip. Following them will likely be lots of the different regular suspects, together with Realme and Sharp, whereas the a lot bigger Samsung can be slated to make use of the chip in some unspecified time in the future within the coming months.
