Qualcomm Snapdragon 415 vs 425 vs 618 vs 620: specs comparison

Qualcomm just unveiled its newest batch of chipsets - the Snapdragon 415, 425, 618, and 620. As usual with processors, a surplus of numbers usually drown us and one can easily get lost among all the specs. That's why we decided to treat you to a straightforward representation of the specs sheets that Qualcomm has provided. In the first table right below, you can see some of the more important specs of the new range of chipsets.

Snapdragon 4158 x Cortex-A53 cores (<1.4GHz)Adreno 405LPDDR3@667MHz eMMC 4.5 SD 3.0 (UHS-I)Hexagon™ V50 DSP
Snapdragon 4258 x Cortex-A53 cores (<1.7GHz)Adreno 405LPDDR3@933MHz eMMC 5.1 SD 3.0 (UHS-I)Hexagon™ V50 DSP
Snapdragon 6182x Cortex-A72 (<1.8GHz) + 4 x Cortex-A53 (<1.2GHz)"Next-gen" AdrenoDual channel LPDDR3 (933MHz)Hexagon™ V56 DSP
Snapdragon 6204 x Cortex-A72 (<1.8GHz) + 4 x Cortex-A53 (<1.2GHz)"Next-gen" AdrenoDual channel LPDDR3 (933MHz)Hexagon™ V56 DSP

Moving on to the rest of the specs sheets, we get to compare the LTE connectivity capabilities of Qualcomm's newest. Judging from the specs, all of these (save for the Snapdragon 415) are pretty even-stevens.

We are not done yet, mind you. The rest of the connectivity features of Qualcomm newest have not slipped under our noses. As you can see, the two Snapdragon 400 representatives are endowed with similar features, and so are the ones of the 600 series.

Snapdragon 620Qualcomm® VIVE™ 1-stream 802.11acBluetooth Smart v4.2IZat™ Gen8C

Last, but certainly not least, we have put together the video/display capabilities of the new chipsets. Just as expected, the brand-new Snapdragon 620 is the most potent of the bunch, as it is able to record 4K video at 30 frames per second as well as 1080p one at no more than 120fps. It also supports two image signal processors (both of which can be up to 21MP in size). The show-stopping feature is its ZSL support - ZSL, if you don't know, stands for "zero shutter lag" and allows you to take a picture as soon as you tap the shutter button.

Holy s**t. The 620 is more powerful than the 810

wait for 820

5. TyrionLannister unregistered

All will come next year anyway.

Or at least the 815. That looks to be a beast too, and might be less than a year away.

18. TyrionLannister unregistered

None is less than a year away. Especially the non-announced ones. QC announced Sd 810 around Q1 2014 and it's released now.

Hey, a guy can dream. I'm hoping it follows QC's previous release pattern, where the flagship chipset was followed about half a year later by a premium version. Think S4/S4 Pro, 600/800, 801/805. I'm expecting the 815 and 820 to be announced around April for 4Q15/1Q16 production.

22. TyrionLannister unregistered

Even ARM said that don't expect cortex a72 till q1 2016. So a custom core is even further away. You can dream but I don't think it's possible.

How does the release date of Cortex A72 affect Qualcomm's custom core release date? It isn't based off of Cortex A72. I would expect the Galaxy Note 5 or Moto X 2015 to be the top candidates for the first device with the Snapdragon 820.

28. TyrionLannister unregistered

Let's see.

Nah, exynos is already better so it's hard to see why Sammy would return to worse.

Better compared to the Snapdragon 810. We still don't know what the 820 will bring; all we know is that it will use a new custom core instead of ARM's reference design, which has worked well for Qualcomm in the past.

I might be possible, because as of now, MediaTek is coming out with A72 based SOC, second half this year.

Not exactly. New CPU cores aside (the A72s' process node is unspecified [hopefully 16nm :) ]), the 620 uses older, lower clocked LPDDR3 RAM, slower dual ISPs and supports a lower display resolution (according to Qualcomm) and LTE Cat. 7 as opposed to the SD810's Cat. 9. This thing is still a beast though (like a 64 bit SD801 with more stuff but for budget buyers). My Xperia Z1's crying in a corner.

The CPU will be at least be on par with the 810 as 810 is a big load of throttling junk. I went to go and confirm on Qualcomm site and you're right. They're starving the cores with a low end 933 MHz LPDDR3 controller. Maybe I got way too excited. For 2016 it looks a proper midrange chip though. I think after getting beat by the Exynos 7420 left, right and centre, Qualcomm will come into it's senses and start producing good chips like the 800( the last mind blowing chip from QC)

It's pretty clear that the fast version of 810 has problem with overheating but i think you should wait for the second and third version of 810. It's too early to declare 810 as a big load of throttling junk.

Exynos 7420 failed to beat 810 :left, right and centre". Only the core speed is faster, if you consider core communication, RAM, GPU, multitasking etc. they're quite even.

23. TyrionLannister unregistered

Are you really referring to that antutu. Please don't. That was tested using Qualcomm bulky reference device and the score of the exynos is no guarantee and can be false. I'd wait for the final tests by more reliable benchmarks. And do check out pocketnow review of g flex 2. You'll be well served.

Only the cpu part is more powerful than the 810. But if Qualcomm build 620 on 28nm I doubt if 620's cpu can defeat 810's cpu in pure raw power.

Is Adreno 330 better than 405? just want to know.

4. TyrionLannister unregistered

Adreno 405 is basically a more efficient 320. So yes, the 330 is a lot better. I want to know which manufacturing process the 620 and 618 are made. I suspect 20 nm TSMC and for the upcoming 820 it should be 16 nm TSMC/14 nm Samsung.

not only that but most likely you will see a underclocked adreno 405 on SD 415

Finally, midrange devices will have better graphics. This is great, since for the past two years it has been adreno 305 or nothing else.

8 cores; 2 CPU clusters. Hm... QUALCOMM goes crazy these days.

Did they give up on 810? But seeing 620 packing such a punch on paper at least, let's see what 820 delivers next year.

20. roldefol

The 810 is a stopgap. You can't expect QC to keep using stock ARM CPUs. Yes, it's their flagship for now, but they're going to replace it as soon as they can work out their in-house 64-bit architecture.

Eight A53 instead of four A57 and four A53 or just four A57... weird. Maybe going for the check list benchmarketing.

A53 cores are cheaper and more power efficient. They're good enough for more budget offerings.

So 620 is equal to 810 in CPU performance.holy f**king sh*t just Imagine snapdragon 820 with 8 custom taipan cortex A72 and a single custom A53 for mundane job and power saving like tegra 4.You can then activate all 9 cores for the full power to rape intel i7.They finally felt the heat from Samsung and got serious.
