The 35 W processor is the Intel Core i7-7700T. The 65 W processor is the standard Intel Core i7-7700. The final T is part of the processor’s model number, so identify the chip by its complete model name—not by its cooler, temperature, or a momentary power reading.
Identify the installed processor in Windows
- Press Win+R, enter
msinfo32, and press Enter. - In System Summary, find the Processor field. Intel says the processor name and model number are displayed there.
- Look specifically for i7-7700T or i7-7700. A missing T means it is the standard model, not the 35 W T variant.
You can also open Task Manager, select Performance, then CPU. The processor name appears in the CPU pane.
Identify it in Linux
- Open a terminal.
- Run
lscpu. - Read the Model name line and check the complete suffix.
The output should distinguish Intel Core i7-7700T from Intel Core i7-7700. Do not infer the variant from current frequency or reported package power.

Check a CPU that is not installed
Read the processor markings
Inspect the text printed on the heat spreader. The full model designation includes the suffix, allowing you to distinguish the T model from the standard model.

Read the retail-box label
If you still have the box, compare its processor name and ordering information. Intel lists these i7-7700T identifiers:
- Tray ordering code:
CM8067702868416 - Boxed ordering code:
BX80677I77700T - Spec code:
SR339
Intel’s Processor Identification Utility for Windows also supports 7th-generation Core processors and newer, according to Intel’s identification guidance.

Specification differences
Intel’s current product specifications list the following values for these desktop SKUs:

|---|---|---|
| Intel-listed TDP | 65 W | 35 W |
| Base frequency | 3.6 GHz | 2.9 GHz |
| Maximum turbo frequency | 4.2 GHz | 3.8 GHz |
| Cores / threads | 4 / 8 | 4 / 8 |
| Cache | 8 MB | 8 MB |
| Socket listing | LGA1151 | FCLGA1151 |
| Integrated graphics | Intel HD Graphics 630 | Intel HD Graphics 630 |
| Intel-listed memory types | DDR3L-1600 and DDR4-2133 | DDR3L-1600 and DDR4-2133 |
The TDP figures are Intel’s product ratings, not a guarantee of a particular computer’s measured wall power, heat output, or sustained performance. Cooling, motherboard power limits, firmware, workload, and the rest of the system affect those results.
Rank #3
Will an i7-7700T replace an i7-7700?
Not necessarily. Although Intel lists both processors for the LGA1151 desktop platform, a socket match alone does not prove that a motherboard or prebuilt computer supports the replacement.
- Find the exact motherboard or system model.
- Check its manufacturer CPU-support list for the specific processor.
- Confirm the required BIOS or firmware version.
- Check the manufacturer’s thermal and power restrictions, especially in compact OEM systems.
Apply the same checks before replacing an i7-7700T with an i7-7700. The lower-rated T model is not automatically supported by every system that accepts the standard model.

Used-parts and replacement checklist
- Request a clear photo of the CPU markings or the box label.
- Verify the complete name: i7-7700T for the 35 W part or i7-7700 for the 65 W part.
- Compare the ordering or spec code with Intel’s product information when the label is unclear.
- Check the exact computer or motherboard support list and BIOS requirement.
- Do not accept a seller’s description based only on “i7-7700,” socket type, cooler size, or a claimed wattage.
