Processor

The Inspiron 14 7435 (2023) can come with the following processors:

• AMD Ryzen 5 7530U with 6 cores and 12 threads, 16 MB cache and a max frequency of 4.5 Ghz.
• AMD Ryzen 7 7730U with 8 cores and 16 threads, 20 MB cache and max frequency of 4.7 Ghz.

Dell supplies the processors with sufficient power and cooling for CPU-intensive tasks resulting in average to above-average performance compared to other laptops with the same processors. In CPU-only tasks, SKUs with the Ryzen 5 7530U and Ryzen 7 7730U perform as expected. SKUs with Ryzen 7 7730U perform impressively well - scoring on average 8-9% higher than the average Ryzen 7 7730U and only 4% behind the average Ryzen 9 7940HS. Performance sustainability is good but not perfect, with all processors losing about 5% performance in long stress tests.

Dell also supplies the processor with sufficient power in mixed CPU and GPU tasks like gaming leading to noticeably better performance than competitors with the same configurations. In particular, the SKU with Ryzen 7 7730U and Radeon Graphics performs better than most other laptops with this configuration and is only 8% behind the Inspiron 14 7435 with Ryzen 9 7940HS and Radeon 680M.

All SKUs lose a significant amount of CPU performance when running on the battery.

Benchmarks:

• Cinebench R23:
  • Ryzen 5 7530U: ~1400 pts (single-core), ~8000 pts (multi-core)
  • Ryzen 7 7730U: ~1500 pts (single-core), ~9000 pts (multi-core)

Graphics

In addition to the integrated AMD Radeon Graphics, the Inspiron 14 7435 (2023) does not ship with any discrete GPUs.

Dell supplies the integrated GPU configurations with sufficient power even though integrated GPUs get diminishing returns beyond a certain power limit. Nevertheless, in GPU-only benchmarks, SKUs with Radeon Graphics perform slightly above average while SKUs with Radeon 680M perform impressively with results that are up to 10% faster than the average laptop Radeon 680M.

In gaming, the Radeon Graphics SKUs with the Ryzen 7 7730U perform significantly better than the competition with the same GPU and are just 8% behind the Radeon 680M Inspiron 14 7435 with the better Ryzen 9 7940HS CPU. The Radeon 680M and Ryzen 9 7940HS SKU also perform above average and outperform laptops with the same Radeon 680M configured with a lower power processor.

All SKUs lose a significant amount of graphics performance when running on the battery.

Benchmarks:

• 3D Mark TimeSpy 2560 x 1440:
  • Radeon Graphics: ~3000 pts
  • Radeon 680M: ~4000 pts
• 3D Mark Fire Strike 1920 x 1080:

Memory

The AMD Ryzen 7000 series processors used in the Inspiron 14 7435 support a maximum of 2 SO-DIMM sticks and the 7000 series processors support up to 32 GB DDR4-3200Mhz memory.

Pre-configured SKUs come with either 8 GB (1 x 8) DDR4-3200 or 16 GB (2 x 8) DDR4-3200 Memory. These sticks perform identically even when paired with different CPUs.

Benchmarks:

• AIDA64 Memory Copy: ~45000 MB/s

Storage

The Inspiron 14 7435 can ship with 256 GB, 512 GB, or 1 TB M.2 NVMe SSD depending on the seller. The OEM SSD only uses 1 slot in all configurations leaving the other slot open for upgrades.

Reviews of the Ryzen 7 7730U and Radeon Graphics SKUs note that both came with the Western Digital SN530 512 GB SSD which is an OEM version of the popular SN550. This is a downgrade from the Samsung PM9A1 used in the 2022 model since the transfer rates drop to 50 % after some time in stress tests due to thermal throttling.

Benchmarks:

• CrystalDiskMark 8:
  • SEQ1M Q8T1 (Sequential 1MB blocks): ~3500 MB/s (read), ~3000 MB/s (write)
  • RND4K Q1T1 (Random 4 KB blocks): ~50 MB/s (read), ~150 MB/s (write)

Keyboard

The Inspiron 14 7435 comes with a standard keyboard layout without a number pad. The keyboard offers 1.3 mm travel and 0.2 mm pitch. The white backlight has a single zone. The refresh rate of the display can be changed using the Fn + R keys - only one step (60 Hz). The Fn + Q keys can be used to switch between the three performance modes - Quiet, Balanced and Performance.

The typing experience is identical to the previous model with the only difference being the inclusion of the Co-Pilot key instead of the right Ctrl key. The travel and feedback are average compared to competitors like HP Envy or Asus ZenBook.

Touchpad

The Inspiron 14 7435 comes with a Mylar plastic clickpad that measures 4.1 inches (10 cm) x 2.5 inches (6.4 cm).

The touchpad is smaller than the ones in competitors like HP Envy but is spacious enough for simple tasks. The clicking is shallow and lacks enough feedback.

Webcam

The Inspiron 14 7435 comes with a 1080p webcam with an electronic shutter and no IR options.

The webcam has poor color accuracy with a minimum DeltaE of 2.31 and a maximum DeltaE of 17.75. The webcam looks soft but is much sharper than 720p webcams that used to be common a few years back. The clarity is adequate for casual calls. There is a physical kill switch on the right side that disconnects the webcam from the laptop. The webcam also supports Tobii Horizon head tracking that can be used in supported games.

Microphone

The Inspiron 14 7435 comes with a dual microphone array.

Case

This section was written by AI and requires review. Remove this after review.

The Inspiron 14 7435 (2023) is available in one color: platinum silver. The chassis remains the same as the previous model except for the redesigned ventilation grilles at the bottom which are now hexagons instead of rectangles. The display lid is made out of anodized matte aluminum alloy while the keyboard deck and bottom cover are made out of PC-ABS plastic. The lid opens to the full 360 degrees to enable tablet mode. The hinge rigidity is good and maintains its position well. Surfaces are slightly roughened to reduce fingerprint buildup however it still attracts dust and fingerprints. The rear is elongated beyond the display lid and is thicker as well to accommodate a larger internal cooling solution. This contributes to the weight of 3.3 pounds (1.5 kg). There are two Dell logos - one on the lid on the bottom left and another on the palm rest on the right.

The chassis has a more professional look compared to the Inspiron 14 7425 (2022) with a uniform color instead of a two-tone silver and gray color scheme. There are fewer accents and angles as well.

Chassis rigidity is excellent with no audible creaking or weak points. The base and lid exhibit some twisting but not enough to be concerning.

Maintenance

The bottom panel is held on by 8 Philips-head screws. Four screws on the leading edge are shorter than the rest. There are clips securing the panel that must be popped up after removing the screws.

Upgradeable components:

• 54 WHr battery.
• One M.2 2230 PCIe4 x4 SSD covered by an aluminum heatsink.
• Two DDR4-3200 SODIMMs covered by a single plastic shield (most configurations only have one slot filled from the factory).
• M.2 2230 wireless card.

Cooling System

This section was written by AI and requires review. Remove this after review.

The Inspiron 14 7435 is equipped with a single 60mm fan connected to the core components with three copper heat pipes. There is one shared heat pipe for the CPU and GPU, one dedicated heat pipe for the CPU, and another smaller heat pipe for the VRMs. The system intakes air from the side and bottom grilles and exhausts air through the back grilles.

Heat

Surface temperatures vary depending on the configuration.

The Ryzen 7 7730U + Radeon Graphics SKU gets quite warm while idling, up to 37 °C on the bottom of the device. The left side with the WASD keys heats up more than the right side. Under heavy load, there is a hot spot of 55 °C on the bottom.

The Ryzen 5 7530U SKU is slightly cooler while idling across all areas reaching up to 34 °C on the bottom. The palm rest and the WASD keys remain comfortable during intensive tasks.

Benchmarks:

• Ryzen 7 7730U + Radeon Graphics:
  • Maximum upper side: ~42 °C
  • Maximum bottom: ~50 °C
  • Idle upper side: ~29 °C
  • Idle bottom: ~32 °C
• Ryzen 5 7530U:
  • Maximum upper side: ~40 °C
  • Maximum bottom: ~48 °C
  • Idle upper side: ~28 °C
  • Idle bottom: ~30 °C

Noise

There is no electronic noise or coil whine. The laptop is effectively silent during undemanding loads like light browsing or video playback, hovering below 30 dB(A). During intensive tasks, the fans quickly ramp up even when set to balanced mode. Fan noise while gaming in balanced mode is identical to performance mode despite temperatures being noticeably lower in balanced mode. During intensive tasks, the laptop emits noise above 45 db(A) and is louder than most other 2-in-1 laptops. Most variants emit the same amount of noise with more powerful configurations being slightly louder.

Benchmarks:

• Ryzen 5 7530U:
  • Load: > 45 db(A)
• Ryzen 7 7730U:
  • Idle: ~22 db(A) (min), ~22 db(A) (avg), ~24 db(A) (max)
  • Load: ~40 db(A) (avg), ~48 db(A) (max)
