Dell Inspiron 5675 Review. The Inspiron 5675 is a Gaming Desktop from Dell. In this review I’ll cover what the system’s got to offer, as well as see how well it performs through various gaming benchmarks both at stock and while overclocked, to help you decide if it’s a computer you should consider.
The system is available in either Intel and Nvidia or AMD and Radeon configurations, and I’ve got one of the higher end AMD models here, so let’s first cover the specs we’re dealing with as they can differ based on your selection. For the CPU there’s an AMD Ryzen 1700X, which has 8 cores and 16 threads, and can boost up to 3.8GHz. There’s 8GB of DDR4 memory running at 2,400MHz, which takes up one of the two slots so you can easily upgrade, and for storage there’s a 256GB M.2 SSD and 1TB 7,200RPM hard drive, but the case can support up to 3 hard drives and a second M.2 drive.
For the graphics there’s an AMD Radeon RX 580 with 8GB of GDDR5 memory, and we’ll see how this performs later in the gaming benchmarks. For network connectivity there’s both gigabit ethernet, and 802.11ac WiFi with Bluetooth 4.1 support. It also comes with a Dell keyboard and mouse, which I’d describe as average, they work fine with no issues.
The case is 45.8cm in height, 21.6cm in width, 43.7cm in depth and the whole system weighs in at 13.74kg. I think the case looks pretty interesting, it’s sort of got this cut away look on the front and left hand side where there’s a bunch of air ventilation holes. There’s blue LED lighting inside which shines through these on the right angle, and also through the Dell logo on the front of the case, but if you’re not a fan you can turn them off through the included software.
The IO on the front includes a 3.5mm audio combo jack, USB 3.1 Gen 1 Type-C port, two USB 3.1 Gen 1 Type-A ports, 2 USB 2.0 ports, and an SD card reader. Above the IO is a DVD burner, with an empty drive bay below. The IO on the back includes PS/2 keyboard and mouse ports, four USB 3.1 Gen 1 Type-A ports, two USB 2.0 Type-A ports, gigabit ethernet port, and 4 audio outputs and mic input jack. On the 580 graphics card there’s a HDMI port, and three full sized DisplayPorts.
Otherwise the back also has the power supply down the bottom, three empty PCIe slots, and a small exhaust fan. On top of the case there’s nothing other than the power button which lights up with a white LED. On the right side of the case there’s just a solid plastic panel, and underneath there’s just four rubber feet Taking a look inside the case we can see that it’s fairly plain looking, but surprisingly there is a fair bit of upgradeability.
For example, as mentioned we can see there’s a second RAM slot free if you want to expand the memory. There’s an M.2 slot in use towards the bottom of the board for the 256GB SSD, but there’s a second empty slot near the RAM. There are two 3.5 inch and single 2.5 inch hard drive bays down the bottom, and the 1TB disk is in one of the 3.5 inch slots. As for PCIe slots, there’s at 16x slot, two 1x slots, although the graphics card covers the first one, and an 8x slot.
I presume you could also upgrade the CPU if you wanted to as well as it’s just a standard socket, although I’m not too sure if the motherboard will be updated in the future for newer AMD AM4 based CPUs. The motherboard reports as having the X370 chipset, so overclocking is definitely possible here. Although it comes down to the silicon lottery, I was able to overclock the 1700X in this PC to 3.9GHz on all 8 cores. With all of that in mind let’s take a look at some benchmarks, I’ve performed testing both with the CPU and GPU at stock speeds, and also with the CPU overclocked to 3.9GHz and GPU overclocked to 1350MHz which was as good as I could get. Kicking things off with PUBG we need to use high or lower settings to average 60 FPS, and we’re getting just a little 3.4% boost from the overclock.
The Witcher 3 is showing similar results, with high settings needed to average above 60 FPS with the overclock just giving a small 2.4% push forward. Watchdogs 2 is a fairly resource intensive game, and as long as you have a good minimum frame rate I think it runs well, you don’t need a high average here. Interestingly the overclock is only really helping at the highest and lowest setting levels, I ran these tests multiple times as I do with all of them and the same results kept coming up, but again realistically there’s not much difference.
I’ve tested Rise of the Tomb raider using Direct X 12 with the built in benchmark tool, and the frame rates reported are pretty good, with the overclock not really making a clear difference, over all setting levels on average it’s giving a 0.3% increase, and again I ran these tests multiple times and got the same results. Shadow of war with the built in benchmark tool is performing alright, and again the overclock isn’t really changing too much, offering just 2.9% of an improvement.
Battlefield 1 generally plays well for me on ultra settings regardless of hardware level, and there’s no exception here, with the overclock able to get us 90 FPS at ultra settings but it’s only 2.5% better than stock speeds. DOOM also generally performs fairly well, with not much change in performance between the setting levels used, even without the overclock at ultra settings the game felt pretty smooth, as shown by these decent 1% lows, which is good as we’re only getting 1.2% of an improvement while overclocked. Ghost Recon is another fairly resource intensive game, and I wouldn’t really want to use this system to play at ultra settings, even with the overclock applied which only gives a 0.8% boost.
Over all games tested on average the CPU and GPU overclocks improved performance by just 1.4%, although this will of course differ, you may get better as overclocking often comes down to luck regarding how good the hardware is, and how long you’re willing to spend testing to get something stable. I probably could have got slightly better overclocks if I’d spent more time playing around. In any case I think the results show that this is a fairly capable gaming system, even at stock speeds.
Now onto the benchmarking tools, while a useful indicator note that these results are less practical compared to the real world gaming results previously shown. We’ll start with the Unigine benchmarks, and we can see there’s a larger gap in performance with the overclocks applied, as synthetic tests seem to scale better than real world games.
Finally I’ve also tested Firestrike, Timespy, and VRMark from 3DMark, and again we can see a fair increase with the overclock applied. Overall from the synthetic tests on average we’re seeing a 5.6% performance increase from the overclocks, confirming that this is indeed much higher than the real gaming tests shown previously. I also note that I didn’t notice any coil whine while performing the tests. These are the system temperatures with an ambient room temperature of 24 degrees celsius. We can see at idle things don’t change much with the overclock applied, and again while playing PUBG on high settings for the gaming tests the temperatures aren’t much different either.
The largest difference between stock and overclock in terms of heat is while maxing out the CPU with Aida64 and the GPU with the Heaven benchmark at the same time, and even while doing this no thermal throttling was observed. As for overall system volume, I thought it sounded alright both at idle and even while gaming. It only started to get noticeably loud while maxing both the CPU and GPU out to 100% for an extended period of time, and you can see that while overclocked the sound levels go up quite a bit, above 60 which is fairly loud.
For reference, here’s how the system sounded at the different levels. Overall I thought the temps were pretty good, considering the graphics card uses the stock cooler, and the cooler on the CPU doesn’t appear to be anything special either. The system is able to pull in lots of air through the cutouts on the side panel despite there not being any air intake fans, and the fans can go quite a bit faster and louder when manually maxed out if you wanted to run cooler but with more noise. While overclocked we can also see there’s quite a bit more power usage, personally I don’t think I’d want to use so much power for just a little performance boost.
In Crystal Disk Mark the 256GB M.2 SATA3 SSD performed around 560 MB/s in sequential reads and 500 MB/s in sequential writes, so pretty good for a SATA3 based SSD. The 1TB hard drive gets above 150 MB/s in sequential reads and writes, which is pretty good for a 7,200RPM drive. At the time of recording with these exact specs the Dell 5675 gaming desktop comes in at $1999 Australian dollars, so about $1550 USD for my international viewers with tax included, although it does appear to go on special from time to time, currently it’s $1,699 AUD or $1330 USD. This isn’t too bad for a pre built system, especially with the current prices of graphics cards, for comparison I quickly spec’d out a similar system on pccasegear, a popular shop here in Australia, and even selecting the cheapest parts that system still comes out to just under $1,800 AUD, so the Dell at the $1700 discount looks pretty good.
So what did you guys think of the Inspiron 5675 gaming desktop from Dell? Overall I think it’s a pretty decent system, the specs are pretty good and it can easily play modern games at high settings. It’s great that there’s the possibility to upgrade so many of the components too. Let me know what you guys thought down in the comments, and leave a share if you found the information useful.
