4-digit Dell Optiplex models – Difference between model-series – Dell Community
Posted by jpluimers on 2025/08/18
A while ago I bumped into the below post but forgot which Google Search query brought me to it. Very to the point info at [Wayback/Archive] Optiplex models – Difference between model-series – Dell Community (thanks [Wayback/Archive] Philip_Yip – Dell Community!)
I think the numbering scheme for the OptiPlex Desktop Range and XPS or Latitude Laptop ranges is of the form QSGV (Quality-Screen-Generation-Variant).Q Quality (3, 5, 7, 9)Q is essentially the quality of the product and uses 3, 5, 7 and 9. This is very similar to Intel’s branding with its processors (i3-Gxxx, i5-Gxxx, i7-Gxxx, and i9-Gxxx) but a Dell Quality 3 does not mean the system has an i3 installed…S is the Screen (2S ” Desktop and 1S ” Laptop/Convertibles)S is the screen size and for most OptiPlex Desktop is 0 as there is no screen. An OptiPlex All in One has a screen however and generally OptiPlex QSGV represents a 2S ” screen for example the OptiPlex 7490 has a 24” screen.On the laptop range screens are typically smaller and XPS QSGV represents a 1S ” screen. In the case of the XPS 13 9310 and XPS 15 9510 i.e. 3 is a 13” screen, 4 is a 14” screen and 5 is a 15” screen.G is the Dell GenerationG is the generation of the OptiPlex or XPS. This is similar to Intel i3-Gxxx, i5-Gxxx and i7-Gxxx but the Dell generation and the Intel generation do not match… The Dell Generation also does match between product lines…The OptiPlex models series start (4 digit models) with 1 and increment upwards.The OptiPlex 790 (2nd Gen Intel), 7010 (3rd Gen Intel), 7020 (4th Gen Intel), 7030 (wasn’t released), 7040 (6th Gen Intel), 7050 (6th or 7th Gen Intel), 7060 (8th Gen Intel), 7070 (9th Generation Intel), 7080 (10th Gen Intel), 7090 (10th or 11th Gen Intel).The XPS series (4 digit models) start with a 3 and seem to be looping back round to 2.XPS 9333 (4th Gen Intel), XPS 9343 (5th Gen Intel), XPS 9350 (6th Gen Intel), XPS 9365 (7th Gen Intel), XPS 9370 (8th Gen Intel), XPS 9380 (8th Gen Intel), XPS 9390 (10th Gen Intel), XPS 9305 (11th Gen Intel), XPS 9310 (11th Gen Intel), XPS 9320 (12th Gen Intel coming soon).V is the VariantFor most OptiPlex models the variant is 0 as there is only a single variant.For the XPS laptops there is normally a laptop and a convertible variant. e.g. XPS 13 9360 is a laptop and XPS 13 9365 is a convertible but the XPS 13 9300 is the convertible variant and the XPS 13 9305 is the laptop variant.
Phil also maintains a cool web site reachable through the landing page [Wayback/Archive] Microsoft Windows OEM FAQs and Downloads – Windows 11 Installation Guides:

I especially like [Wayback/Archive] Installation of Windows and Linux on a Virtual Machine Using VMware Player – Windows 11 Installation Guides because of these cool details he explains:
- This is incredibly powerful when one wants to run software that is only compatible with a Legacy Version of Windows or test another type of Operating System. For example a scanner with drivers and software for only Windows XP may be ran on a Windows XP Virtual Machine that runs on a Windows 10 Host.
- The most common legacy Windows versions required for legacy software and legacy hardware are Windows 7 Pro and Windows XP Pro. The biggest difficulty for these OS is obtaining the installation media and activating. I describe the best ways using OEM Downgrade Rights from a Windows 10 Pro OEM License.
- For Windows 7 Pro you can either perform a clean install and activate using OEM Downgrade rights from a Windows 10 Pro Host PC for product activation by porting the SLIC 2.1 across. Or alternatively use VMware vCenter Converter to create a Virtual Machine image of the physical machine and activate using OEM Downgrade rights from a Windows 10 Pro Host PC for product activation by porting the SLIC 2.1 across.
- On a Windows 10 Pro OEM PC we can install a Windows 7 Pro VM and then install the XP Mode VM within it as a Nested VM that will remain activated.
